* configure.ac: Default to efi platform for x86_64-apple.  Allow
	powerpc64 CPU, default to ieee1275 platform for it.  Split CPU
	adjustments from the rest, only do them if target is not
	explicitly given.  Merge other adjustments with the final sanity
	check.  Remove an extraneous check for supported CPU.  Be
	specific which CPU and which platform is not supported.
