Add bmakefiles for building binutils from the contrib tree. This finishes up the binutils import. But I am leaving it disabled in "src/gnu/usr.bin/Makefile" for now. It is not used by anything yet, so I'll take this opportunity to run one more round of tests before enabling it.

Add TARGET_ARCH=mipsel and TARGET_ARCH=mipseb as a valid targets. Unlike the unisex architecutres we've had so far, mips is bisexual. These tools can produce either byte sex, and the compiler/make determines the proper gender to use. Otherwise, we'd have to have had mipsel and mipseb in all the places that we have just mips. And there are other complications with doing that (binutils doesn't like to build mips tools without both byte genders, it seems). Introduced BINUTIL_ARCH so that other bisexual architectures can a generic mechanism. We cannot just define MACHINE_ARCH as mips because we need to differentiate big and little endian types of binaries. Discussions on freebsd-arch have hashed out this issue (and the parallel libc issues). NetBSD is moving towards mipsel and mipseb for their two flavors of mips ports (in time for 1.4, if this change hasn't already been accomplished). I've been building i386 worlds with this tree for a three months with these files in place with no ill effects.

After a repo copy of as_{alpha,i386,mips} to {alpha,i386,mips}-freebsd, tidy up the logic that works out which sub-directories to build. The new directories with freebsdelf suffixes now have freebsd suffixes after a repo move by Peter at the request of David O'Brien.

Change CROSS_TARGETS to CROSS_FORMATS because that makes more sense. Check if already cross-compiling and only build the cross-tools if not cross-compiling (to save time).

# Only build the cross tools when not cross-compiling.
s/MACHINE_ARCH/TARGET_ARCH/g The target machine is represented by TARGET_ARCH. MACHINE_ARCH always represents the host machine. When TARGET_ARCH is not defined, it is assumed to be equal to MACHINE_ARCH. This means that we're building a native toolset by default. We're creating cross-compilation tools when MACHINE_ARCH != TARGET_ARCH. TARGET_ARCH is defined when building binutils as part of the bootstrap build and is set to reflect the architecture we're currently cross- building. With this change binutils is ready for cross-building.

Add support for cross-architecture gases. Since the GNU code doesn't support more than one architecture at a time, build as from the default for the host and if CROSS_TOOLS defines other architectures, build them as as_${arch}
