OK, thanks to the couple of people who responded to this.  I have
gotten to the point that cross-binutils are compiled, but compiling
egcs gets messed up in the objc directory.  Now, that's not really a
problem, since I don't really want Objective C anyway, but how do I
tell configure to ignore it?  --without or --disable seems to just
accept any random suffix withou a hitch, but doesn't seem to do
anything if I append objc either.  What are the magic words, are there 
any? 

The docs don't seem to explain how to do this.

PS: gnu.gcc seems awfully undertrafficked - is there another group I
should know about?

Sorry, this only works with recent snapshots.

Post the question to egcs@egcs.cygnus.com - the official egcs mailing
list.

Yeah, I know.  I'll stop now.

Yep, but I found the patch for gcc-2.8.1, so I'm trying with that.  It 
does require something called "autoheader", though, which I have no
idea what is.

Yes it can be used to cross compile for the powerpc.  We have a product we
purchased that runs on a Motorola MPC860 which software was compiled
on a Sun Solaris system.  I am just getting started on trying to set up a
similar
system to cross compile for the 860 on a Linux system using GCC-2.8.1.
I have built the Makefile using configure but I am getting some errors for
missing header files (reg_types.h, regex.h and lc_core.h).

Eww!  Use egcs (http://egcs.cygnus.com) which will generate _much_
better code for the PPC.

In recent egcs snapshots (but not 1.1.1) include the --enable-languages option:

	--enable-languages="c c++"

Another alternative is to delete the objc directory.  What is failing is
objective C wants to use the standard header files like stdio.h, which you
haven't created for the target.
