Change 109346 by imp@imp_lighthouse on 2006/11/06 08:23:26

	Take a page from NetBSD and introduce MACHINE_CPU.  This is the CPU
	family derived from the MACHINE_ARCH.  MACHINE_ARCH
	necessarily includes endian information, because arm big endian and
	arm little endian binaries are different.  mips64 and mips binaries
	are different, so MACHINE_ARCH might be "mips64el" and MACHINE_CPU
	would be plain old "mips".  Basically, any family of cpus that
	one set of source files can support.  Initially, this will be
	arm (little endian) and armeb (big endian) both mapping to arm for
	this.  Likewise with mipsel and mipseb both mapping to mips (this
	is a favor for the mips branch).
