	* rs6000-tdep.c (rs6000_gdbarch_init): Don't call
	find_variant_by_name, because it confuses the multiarch
	framework. Return NULL if there isn't an architecture with the
	user supplied name, instead of forcing a different one without
	recording the change with the multiarch machinery.
	(find_variant_by_name): Delete.
