	Just to confirm - on sparc64 the sparc/sparc64 ABI applies to the
	entire tree? If so then wouldn't it work unless you're sharing an obj
	tree between sparc64 in 32bit mode and sparc64 in 64bit mode?
	(Assuming a given dir does not have MACHINE_ARCH and MACHINE obj

	I agree it would be cleaner to switch the 64-bit MACHINE_ARCH :/
