	* 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.
