Yeah I could, but I've been using my make infrastructure's about as
long as crosstool has been around, so I'm more comfortable with it :)

I'll have to give that a go.

Well there's one now for the am33.  See:
http://sources.redhat.com/ml/libc-alpha/2004-10/msg00130.html
for Roland's announcement.  They hide in the ports module of the glibc
CVS repository.  Since ColdFire is far enough different than m68k, I
have to have a seperate sysdep/coldfire anyway, so I'm thinking of making
coldfire a stand-alone add-on and --target=coldfire-linux work for
binutils, gcc, glibc....

M68k hardware is still out there, and ColdFire v4e hardware exists!
