Merge "Move MIPS .dynamic to the data segement, so that it is writable. Replace hard-coded 4096 with symbols for correct segment sizes for MIPS."

Fixes:
1. Update TOOLCHAIN_GIT_DATE to 2012-06-10
2. More fix in ld --gc-sections (see comment in
   https://android-review.googlesource.com/#/c/36585/)

This adds a new gdb NDK-local patch to fix the mingw64 builds.
Also, rename 0001-ndk-Disable-usage-logging-for-Windows.patch
to match the logical order of previous ones.

This patch adds the -funwind-tables flag when building our prebuilt
libraries in order to ensure that the generated code can easily be
unwound at runtime.

This prevents stack-traces from being incorrectly shortened, for
example when using the malloc leak checked, the STLport/GABI++
operator new implementation could not be unwound, and the stack
trace could not show where the code was really allocated/freed
in the original source code.

This patch adds build-host-gcc.sh, a new script that can rebuild
our GCC-based toolchain from scratch, without using the AOSP
toolchain/build.git scripts.

NOTE: The script does *not* rebuild GDB at all (a future patch will
      provide build-host-gdb.sh to do so).

The script is capable of building *several* toolchains at once,
minimizing what needs to be done to speed up the whole process.
For example, here's how to rebuild the linux-x86 and windows
toolchains for both gcc 4.4.3 and gcc 4.4.6 on all of arm,x86 and mips:

  build/tools/build-host-gcc.sh --toolchain-src-dir=/path/to/toolchain/src \
    --systems=linux-x86,windows \
    arm-linux-androideabi-4.4.3 \
    arm-linux-androideabi-4.6 \
    x86-4.4.3 \
    x86-4.6 \
    mipsel-linux-android-4.4.3 \
    mipsel-linux-android-4.6

This operations takes 31 minutes on a 16-core 2.4 GHz z600, not bad
for something that generates 12 different toolchains.

Define NDK_CCACHE=ccache in your environment to speed-up rebuilds.
On my machine, the above command takes above

+ The script will build for the host system by default. This means
  linux-x86_64 on 64-bit Ubuntu 10.10, for example.

This script has been tested to build the following toolchains
succesfully:

  arm-linux-androideabi-4.4.3
  arm-linux-androideabi-4.6
  x86-4.4.3
  x86-4.6
  mipsel-linux-android-4.4.3
  mipsel-linux-android-4.6

For the following host systems:

  linux-x86
  linux-x86_64
  windows (see note below)
  windows-x86_64
  darwin-x86
  darwin-x86_64

Regarding windows, the build succeeds with the i586-mingw32msvc-gcc
cross-toolchain installed on Linux, and with x86_64-w64-mingw32 which
can be rebuilt from sources with build-mingw64-toolchain.sh

This is to check that static executable generation works properly,
e.g. that our crtbegin_static.o sources aren't broken for some
reason.

Note that this test fails with the x86-4.4.3 toolchain generated
with build-host-gcc.sh at the moment (not with the one built with
build-gcc.sh). The symptom is:

   $NDK/toolchains/x86-4.4.3/prebuilt/linux-x86/bin/i686-linux-android-strip --strip-unneeded  ./libs/x86/static_main
   BFD: BFD (GNU Binutils) 2.19 internal error, aborting at /tmp/ndk-digit/src/binutils/binutils-2.19/bfd/elf.c line 4655 in assign_file_positions_for_non_load_sections

   BFD: Please report this bug.
   make: *** [libs/x86/static_main] Error 1
   make: *** Deleting file `libs/x86/static_main'

So it looks like a binutils-2.19 crash when 'strip' is called.

Fixed two issues
1) Unset NDK_TMPDIR after setting RELEASE_DIR to be under
   $NDK_TMPDIR, otherwise scripts called later may reuse
   the same NDK_TMPDIR for their own things and completely
   remove it after done!
2) A typo "timestamp_set build-mingw-prebuilts"

Also, wrap "run" around scripts it calls

"--noexecstack" for assembler and "-z noexecstack" for linker enable NX
protection against buffer overflow attacks by enabling NX bit on stack and heap.

"-z relro -z now" for linker hardens internal data sections after linking
against security vulnerabilities due to memory corruption.  See

  http://www.akkadia.org/drepper/nonselsec.pdf (section 6)
  http://tk-blog.blogspot.com/2009/02/relro-not-so-well-known-memory.html

For those who really needs it, these features can be disabled by
1. Passing "--execstack" to assembler and "-z execstack" to linker to
   disable NX protection.
   Passing "-z norelro -z lazy" to linker to disable second protection.
2. In NDK jni/Android.mk, set the following
   LOCAL_DISABLE_NO_EXECUTE=true: to disable "--noexecstack" and "-z noexecstack"
   DISABLE_RELRO=true: to disable "-z relro -z now"
   see $NDK/docs/ANDROID-MK.html for details

This patch rewrites the standalone toolchain tests completely
(the previous version didn't work properly anyway).

tests/standalone/run.sh can be used to check that a given
NDK toolchain works properly. It doesn't have to be a
standalone toolchain as long as you use the --sysroot=<path>
option.

Usage example:

  tests/standalone/run.sh --prefix=toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc

Note that the tests do not assume that a C++ STL is available
in the toolchain's installation directory. We will probably
add a few other tests to check these later.

This patch modifies gen-platforms.sh in order to automatically regenerate
the C runtime files (e.g. crtbegin_static.o) from their assembly sources,
when available.

For example, this always rebuilds the MIPS runtime objects whose sources
are located under development.git/ndk/platforms/android-9/arch-mips/src/

NOTE: This only works for assembly files with a .S extension.

The goal is to get rid of the prebuilt binay object files, and make it
easier to track / improve these files.

Another patch will modify development.git to get rid of all other
prebuilt object files, and replace them with the corresponding
assembly.

+ Do not copy prebuilt object and library files to a minimal sysroot.
  You can rebuild all our toolchains properly without these
  (tested with both build-gcc.sh and build-host-gcc.sh)
