Description

Add a performance optimized crc32c function for ppc64le that uses Altivec assembly instructions. Add an architecture probe for ppc (PowerPC 'ppc64le' architecture). When the architecture probe detects that the ppc specific crc32c function (ceph_crc32c_ppc) can be used, it will do so instead of using the default crc32c function (ceph_crc32c_sctp).
