	* 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.
