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).

Bug: 17333374
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.
