Summary: Add support for building ossl(4) on powerpc64* by implementing ossl_cpuid and other support functions for powerpc. The required assembly files for ppc were already present in-tree. Test Plan: The changes were tested using the in-tree tools/tools/crypto/cryptocheck.c tool on both powerpc64 and powerpc64le on a POWER9 system.
