	* sysdeps/powerpc/powerpc64/multiarch/stpcpy-power8.S: Define the
	implementation-specific function name and remove unneeded macros definition.
	* sysdeps/powerpc/powerpc64/multiarch/stpncpy-power7.S: Likewise.
	* sysdeps/powerpc/powerpc64/multiarch/stpncpy-power8.S: Likewise.
	* sysdeps/powerpc/powerpc64/multiarch/strcpy-power8.S: Likewise.
	* sysdeps/powerpc/powerpc64/multiarch/strncpy-power7.S: Likewise.
	* sysdeps/powerpc/powerpc64/multiarch/strncpy-power8.S: Likewise.
	* sysdeps/powerpc/powerpc64/power7/strncpy.S: Set a default
	function name if not defined.
	* sysdeps/powerpc/powerpc64/power8/strcpy.S: Likewise.
	* sysdeps/powerpc/powerpc64/power8/strncpy.S: Likewise.
