powerpc: refactor memset 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/memset-power4.S: Define the implementation-specific function name and remove unneeded macros definition. * sysdeps/powerpc/powerpc64/multiarch/memset-power6.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memset-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memset-power8.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memset-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/memset.S: Set a default function name if not defined and pass as parameter to macros accordingly. * sysdeps/powerpc/powerpc64/power4/memset.S: Likewise. * sysdeps/powerpc/powerpc64/power6/memset.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memset.S: Likewise. * sysdeps/powerpc/powerpc64/power8/memset.S: Likewise.
