[PATCHv2] powerpc: ABI change - add HWCAP/HWCAP2/platform info to TCB


Hi

After the original discussion on this matter, I decided to change the patch. Main differences:

- versioned symbol to track this change.
- no âsetâ API in ppc.h
- no per-thread initialization
- added platform number (derived from AT_PLATFORM string) for future implementation of __builtin_cpu_is() in gcc.

Tested on ppc32, ppc64 and ppc64le, both dynamic and static cases.

Please review.

Thanks,
