Merge gcc patches from NDK

[Jim Huang]

In NDK[*], there are some Android specific patches landed in directory build/tools/toolchain-patches/

In order to build Android compatible toolchain, we should include these and verify.

[*] http://android.git.kernel.org/?p=platform/ndk.git;a=summary

[Jim Huang (jserv)]

Existing patches:
 * 0001-arm-linux-androideabi-make-fpic-the-default-instead-.patch (arm-linux-androideabi: make -fpic the default, instead of -fPIC)
 * 0001-Enable-C-exceptions-and-RTTI-by-default.patch (Enable C++ exceptions and RTTI by default)
 * 0001-Fix-compilation-of-gcc-4.4.0-on-OS-X-10.6.patch (Fix compilation of gcc-4.4.0 on OS X 10.6)
 * 0001-libstdc-v3-fix-setlocale-related-crash.patch (libstdc++-v3: fix setlocale()-related crash)
 * 0001-Work-around-for-Android-__cxa_finalize-bug.patch (Work-around for Android __cxa_finalize bug)

I think we can pick up these and apply into linaro-gcc-4.5 tree. After verified, please send new patches to list for review.

NDK is really a nice to have feature for our first release. Might become a harder requirement after may though.

Toolchain WG is known to merge linuxandroid related patches into gcc-linaro-4.5, so that we can focus on the changes from NDK.

NOTE: linaro-gcc-4.6 includes several Google's patches.
