Whoops, in this case it's looking for a 440 directory in sysdeps.  You
should be able to build it without the --with-cpu=440 and it'll
default to the lowest common denominator.

If you want to enable 440 you can simply add a 440/ directory to
ports/sysdeps/unix/sysv/linux/powerpc/powerpc32/440 and one to
ports/sysdeps/powerpc/powerpc32/440

Yes want nptl as well...

--with-add-ons=ports,nptl

I'll be pushing a patch soon which enables 440 by default, but I'm
trying to iron out the kinks.
