This patch adds build-host-sed.sh that can be used to rebuild
host versions of the sed tool, which will be placed under
prebuilt/<system>/bin/

This is mainly for native Win32 support, since we can't rely
on having a working sed in this environment.

A future patch will modify the NDK build system to use the
prebuilt binary automatically.

+ Add prebuilt/ to .gitignore
+ Remove prebuilt/ in dev-cleanup.sh

This patch modifies the helper functions inside prebuilt-common.sh
to distinguish between host and target builds more easily.

A target build is used to build target Android binaries, while a host
one is used to build binaries that will run on the host machine, i.e.
invoked by the NDK build script.

We will use host builds to generate the Windows helper binaries that
the NDK depends on (sed, awk, make, etc...) in future patches.

This patch allows any script to source prebuilt-common.sh
properly. Before that, only patches in the same directory,
i.e. build/tools/, could source it without errors.

Note: To do that, the parent script must define NDK_BUILDTOOLS_PATH
to point to the build/tools/ directory. If the variable is not defined,
prebuilt-common.sh assumes that it is sources from build/tools/

This patch adds a new function to prebuilt-common.sh that can
return the install location of prebuilt host binaries. It
currently is: $NDK/prebuilt/$HOST_TAG/

This will be used to store host binaries, like the Win32 versions
of GNU Make, Awk, Sed and others.

This patch changes the definition of HOST_OS to 'cygwin' when
we detect that the build system is invoked from a Cygwin-compatible
GNU Make program.

The old value of 'windows' will now be used for the case where the
build system is invoked from a vanilla Win32 GNU Make binary, e.g.
from a standard Windows shell.

First step towards getting rid of Cygwin.

This patch modifies our build of stlport to include the GAbi++
runtime in order to support RTTI.

Change-Id: I8ff1853ad886e217f3d0d8a9366fc5075c63cc34

Also, for now we still need to depend on the system libstdc++
to implement one-time-construction properly. We should probably
implement that in GAbi++ itself, but this will come in another
patch.

Note that the system libstdc++ uses private Bionic functions
that cannot easily be used in the NDK. Especially those related
to device-specific memory barriers. A correct NDK implementation
will likely use pthread mutexes instead.

This patch ensures that run-tests.sh uses an exact match.
Before that, when using --test=test-stlport, it would
try to run both test-stlport-rtti and test-stlport

Change-Id: Id67e0e783b559639240d49f6c6803f5e71b1c065

This patch modifies download-toolchain-sources.sh so that it
creates a SOURCES file listing the SHA-1 states of every toolchain
git repository that has been downloaded.

Similarly, build-gcc.sh is modified to copy the file to the final
install location / archive.

Change-Id: Ifcc40a7e671c6e3f23613ac8bcc705bb9b9be448

This patch modifies the build system to allow one to
list several C++ source file extensions in LOCAL_CPP_EXTENSION.

+ Check the value of LOCAL_CPP_EXTENSION and warn about values
  that do not start with a dot (and ignore them).

Note that this doesn't change the default (which is to use '.cpp')

This patch adds a new C++ runtime that can be used by modules
by setting APP_STL to either 'gabi++_static' or 'gabi++_shared'
in their Application.mk

GAbi++ is an alternative to the GNU libsupc++ that provides
RTTI support (with exceptions added in the future).

The goal is to use it to support RTTI (and later exceptions)
with our version of STLport, or even a different non-GNU STL.

+ new build-gabi++.sh script to rebuild the prebuilt libraries
  from sources.

+ support in rebuild-all-prebuilt.sh

+ support in package-release.sh

+ Unit test to check that RTTI actually works, both in the
  static and shared library case.

Change-Id: I7e73a31a4d24b5baa36fef357b69064c192ddc56

This patch introduces build/tools/builder-funcs.sh which contains
several functions that can be used to build source files into
static or shared libraries either directly or with the help of
an auto-generated Makefile (in order to allow for parallel builds).

Most of the functions come originally from build-stlport.sh which
has been modified to use the new stuff in builder-funcs.sh

Other NDK scripts will use this in the future to rebuild other
prebuilt binaries.

+ Support for NDK_CCACHE to speed up rebuilds. E.g. build-stlport.sh
  now takes 0.9s on my machine (used to be 26s before that).

Change-Id: I8ef97e62987f6aac6713821455d9a1ddcbbde796

This is a new variable that can be used to specify that a
given module relies on C++ exceptions or RTTI.

This is done for several reasons:

- First, we want to avoid always linking GNU libsupc++
  to every final binary, because we're soon going to
  provide an alternative.

- Second, it is useful to declare prebuilt binaries that
  have been compiled with these features. It allows the
  final link to work correctly.

Note that the change is backwards-compatible. You can still
use -frtti or -fexceptions in your compiler flags to enable
the features too.

Fix 1: Ensure shared libraries can be loaded: When running
test programs on the device that rely on a shared library,
ensure that LD_LIBRARY_PATH is properly define to allow the
program to load normally.

Previously, launching the program from the script would fail
with a "Can't link ..." error.

Fix 2: Build unit tests in a non-random directory:

This patch changes run-tests.sh to build all unit tests in a
non random directory (/tmp/ndk-$USER/tests/build/).

This speeds up (about 2x) running the test suite when NDK_CCACHE
is being used, because the content of the auto-generated dependency
files are no longer random anymore.

This patch modifies the way the NDK build script computes the
value of NDK_PROJECT_PATH when it is not already defined.

If we are in the project's top-level directory when ndk-build
is invoked, we can use the value '.' for NDK_PROJECT_PATH.

This reduces the length of all paths passed to build commands
(source files, object files, binaries), which can be useful
for modules with a ton of sources (especially on Cygwin where
the maximum command-line lenght is quite limited).

Change-Id: I35a60df243c156690dc3020983b6232cd9b92ec6

Ensure that if 'foo' imports static library 'bar' which
imports static library 'zoo', then libfoo.so will be linked
against both libbar.a and libzoo.a

Before this patch, only libbar.a was used, which resulted
in a link error.

This patch ensures that imported shared libraries are now copied
to the install location (libs/<abi>) by default. Previously, one
had to list them explicitely in APP_MODULES to do that (only
top-level project modules were installed).

We don't need to rename the auto-generated dependency file when
we're not running inside Cygwin, so simplify operations.

In other words, before this patch, we would compile a source file
on Unix with something like:

  gcc -c -MF foo.d.org   -o foo.o foo.c &&
  mv foo.d.org foo.d

Now we will simply do:

  gcc -c -MF foo.d -o foo.o foo.c

Compilation on Cygwin isn't changed.

This makes the build commands dumped with V=1 easier to read.

This patch allows host rebuild scripts to use NDK_CCACHE when
it is defined.

Unfortunately, this doesn't speed build-gcc.sh tremendously on
my machine, because most of the build time is done with the second-phase
"xgcc" binary that is generated during the first phase. Still shaves off
20s out of 4m40s on my machine with -j32.

Improvements should definitely be better for other host binaries.

Define NDK_CCACHE=ccache in your environment and the NDK build
system will automatically use the tool to speed-up your rebuilds.
See http://ccache.samba.org for more details.

This patch allows the use of 'APP_ABI := all' in your
Application.mk or on the command-line to indicate that you
want to build for all NDK-supported ABIs.

This is shorter than typing the full list of known ABIs,
and allows for an easy upgrade path when we'll introduce
new supported ABIs in the future (if any).

This improves the output of the module database when you
define NDK_DEBUG_MODULES=1 when calling ndk-build.

This really means that:

 - only dump the fields that are not empty
 - break multiple field value into several lines
   (it the value only has an item, print it in-line as before).

+ Fix doc typo

This patch modifies the NDK build system to support a file
named 'project.properties' in the application's project directory
to hold the value of the target platform.

If the file is not present, 'default.properties' will be searched
instead.

This patch is in preparation of future changes to the SDK tools,
which will rename/split default.properties and build.properties.

The script mistakenly copied the ARM GNU libstdc++ binaries into
the x86 toolchain installation directory. The end result was that
one could not build C++ programs with it.

Document that a minor issue with the standalone arm toolchain linker
is fixed (regarding the __dso_handle symbol). The fix is really in
https://review.source.android.com/24619

+ Modify tests/run-tests.sh and tests/run-standalone-tests.sh to
  use /tmp/ndk-$USER/tests as their working directory.

Change-Id: Id593041251c0965762b3a4e649207f7b20be8e85

Remove the compiler warning about the size and type of __dso_handle which
couldn't be found. Turns out we didn't define CRTBEGIN_SO_O and CRTEND_SO_O
properly.

Fix the --package-dir option processing. The script was not using proper
paths when calling pack_archive/tar, which resulted in the file placed
at the wrong location inside the final archive.

+ Make build commands visible with --verbose --verbose
+ Remove double declaration of -j<number> option
