Change 133911 by marcel at marcel_cluster on 2008/01/23 04:13:31

	Import NetBSD's FPU emulator for PowerPC. This allows
	us to use a single userland for both cores with FPU
	and cores without FPU. This is not intended to be the
	fastest solution, but rather the most flexible.
	The ability to use soft-float is there, but breaks
	the existing ABI.
	
	Untested...
