Our patched set of binutils does configure BFD and binutils, but I 
haven't looked at how far we diverge from the FSF sources in this 
directory.

FWIW the Apple set of patched sources can be gotten by anoncvs.  As per
	http://developer.apple.com/darwin/tools/cvs/howto.html

cvs -d :pserver:anonymous@anoncvs.opensource.apple.com:/cvs/root login
("anonymous")
cvs -d :pserver:anonymous@anoncvs.opensource.apple.com:/cvs/root co -r 
muon-branch gdb

You'd want to check out "muon-branch" as that's the last stable version 
of the sources; the head development represents some mid-merge mess 
that you don't want a piece of.

(I hate to sound like a slacker and not dig into the FSF binutils 
sources to find how they compare to our patched sources, but I'm in the 
middle of dealing with the aforementioned merge mess and am pretty busy 
just now..)

We use BFD for gdb, so it's a safe bet it can read MachO and CFM files, 
at least as far as gdb needs it to.  Last time I looked, many of the 
binutils utilities worked although we don't test/support/use/ship any 
of those -- everything can be accomplished with the native OS X cctools 
programs (otool, nm, pagestuff, etc.)
