- Use clang-2690385 to build RenderScript toolchain.
- Use armv7-linux-androideabi as the triple used to build RenderScript
runtime libraries.

RPATH was used in order for ASan executables to prefer ASan libraries
under /data. Now ASan executables use a special loader (linker_asan),
which implements this logic. RPATH is no longer needed.

Clang's tail call optimization for position independent code
only works when the callee was called (bound in GOT) before
the jump through GOT.
It does not work for some lazy bound Android tail callee.
We used special flag to disable all tail call optimization.
This change removes that global flag and depends on
clang compiler fix from upstream or the temporary patch in

http://llvm.org/bugs/show_bug.cgi?id=15086,
llvm tail call optimization is wrong for x86.
For Android/x86 to use SSE* instructions safely, stack should be 16-byte
aligned before JNI function call, which isn't true for all x86 device,
so -mstackrealign should be the default.

This will be necessary to support -std=gnu99 mode for clang 3.6, which
defaults to C11 mode (unlike prior releases that use C99).

Add RS_TRIPLE_CFLAGS to ensure that we build with the proper defines on
targets like x86. This also changes all build targets to use the
proper 32/64-bit triples when creating their runtime libraries.

combo/TARGET_x86*.mk mistakenly added TARGET_GLOBAL_CFLAGS to their
linker command lines. This results in clang builds not working properly,
since they strip some unknown flags from TARGET_GLOBAL_CFLAGS.

1. Following the setup of gcc in build/core/combo/,
we added the [HOST|TARGET]_<arch>.mk clang config files,
and load only the configs needed by the current product.
2. Added support for the 2nd arch.
