Change 109347 by imp@imp_lighthouse on 2006/11/06 08:30:32

	Use the new MACHINE_CPU instead of MACHINE_ARCH as the basis for
	TARGET_ARCH.  I'm unsure if the amd64 -> x86_64 translation should
	happen like it does in this file, or if that's another case for
	substitution in bsd.own.mk.  I kinda think this is the right place,
	since it is a gnuism and the rest of the tree is setup so that
	amd64 is the right thing to do.
	
	The binultils infrastructure wants 'TARGET_BIG_ENDIAN' defined
	when we're building big endian architectures for those CPUs
	that can support many different byte sexes.  Since I'm uneasy
	about doing a regular expression match against "*eb" I have
	listed the two cases where we have multi-endian architectures
	(mips and arm).  powerpc may also be one, and some that NetBSD
	supports that FreeBSD does not.
	
	Note: armeb support isn't there yet, and I believe this will not
	break the present TARGET=arm TARGET_ARCH=arm TARGET_BIG_ENDIAN=t
	way of building for xscale based big endian boards.
