powerpc: refactor memchr, memrchr, and rawmemchr IFUNC.
Clean up the IFUNC implementations for powerpc in order to remove unneeded macro definitions. Tested on ppc64le with and without --disable-multi-arch flag. * sysdeps/powerpc/powerpc64/multiarch/memchr-power7.S: Define the implementation-specific function name and remove unneeded macros definition. * sysdeps/powerpc/powerpc64/multiarch/memrchr-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/rawmemchr-power7.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memchr.S: Set a default function name if not defined and pass as parameter to macros accordingly. * sysdeps/powerpc/powerpc64/power7/memrchr.S: Likewise. * sysdeps/powerpc/powerpc64/power7/rawmemchr.S: Likewise.
