Add autodetection of ppc64 architectures That allows 'make -j profile-build' work on ppc64 architectures, setting the use of the appropriate SIMD extension, Altivec or VSX. For VSX, gcc allows to map SSE2 intrinsics and get benefit of the existing SIMD code. On PowerMac G5, using altivec provides a performance improvement of 30%. On Talos 2, using vsx provides a performance improvement of 120%. closes https://github.com/official-stockfish/Stockfish/pull/5624 No functional change
