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