Our implementation of LOCAL_SHORT_COMMANDS relied on 'echo -n' to append
data to an existing file, but this option is not supported by Darwin's
echo program.

Modify our build scripts to use "printf %s" instead to do the same thing
on Posix systems. On Windows, which doesn't have printf, keep using the
toolbox echo program that supports the flag.

All target prebuilt will be built with GCC 4.6.

GNU libstdc++ is GCC dependent.  GCC 4.6 seems to take header/libraries
built by GCC 4.4.3, but the reverse isnʼt true.  With this CL GCC will
now use its own version of libstdc++.

make-standalone-toolchain by default install GCC 4.6.  Use --toolchain to
select GCC 4.4.3.

ndk-gdb should also pull /system/bin/link, so gdb on host can set
a breakpoint in __dl_rtld_db_dlactivity and be aware of linker
activity (eg. rescan solib symbols when dlopen() is called)

Better fix than https://android-review.googlesource.com/#/c/38631
on issue http://code.google.com/p/android/issues/detail?id=32300

"make" does set ERRORLEVEL but in cmd.exe it seems that ERRORLEVEL
is evaluated before the whole compound statement instead of just
before it is use.

Change-Id: Ia56d3dc89e4b13caabd29aeaf57c277906202fdd

It appears that "make" doesnʼt set ERRORLEVEL running ndk-build.cmd
in cmd.exe shell, which causes ERRORLEVEL to remain zero even when
make fails.  Fixed it to return non-zero value when fails.

Enable gold for x86-4.6 and arm-linux-androideabi-4.6 (with binutils-2.21)
on Linux and MacOSX.  ld.bfd remains the default linker.  User can enable
gold by

   LOCAL_CFLAGS += -fuse-ld=gold

Reasons for not enabling gold on other binutils/host/target
1) gold in binutils-2.19 (compiled with NDK GCC 4.4.3) isn't considered
   stable.
2) gold can't currently compile in Windows where fcntl() isn't supported.
3) gold doesn't support MIPS.

When LOCAL_SHORT_COMMANDS is set to true, compiler options are emitted to a
response file and read off using the '@file' syntax.  This is to support very
long commmand line w/o running over the limit of shell command buffer.

Obviously target depends on the response file which shall be regenerated
every time to account for potential changes in command line options.
Unfortunately this triggers rebuilding of target as well even when the content
of response file is identical to the last one.

This CL fixes it by emitting options to a temp file, and only update the response
file when contents differ

During toolchain construction "--with-sysroot" contains minimal set
of headers and libraries not needed afterward (*1).  Because GCC by
default will search the path and actually find it by accident (*2),
it's better to point that to local directory such as /tmp.

(*1) NDK specifies --sysroot, and Android build explicitly lists
     all dependencies.
(*2) The path may exist but contain stale headers/libs, reside
     at remote server and slow down GCC, or inaccessible which crash
     GCC!
