ndk: Remove prebuilt C runtime objects. Add sources instead.
This patch removes all prebuilt C runtime object files from
the ndk/platforms/ directory. We replace them with equivalent
assembly sources lifted from the following directories:
bionic/libc/private/ (for __dso_handle.S and __dso_handle_so.S)
bionic/libc/arch-$ARCH/ (for all others)
Note: This requires that your NDK's gen-platforms.sh script be
capable of rebuilding the object files from sources.
See https://android-review.googlesource.com/36822
The goal here is to make it much easier to update these files,
and track their changes relative to the content of bionic/lib.
For example to fix the following issues in the future:
