I don't even get that far now.  I'm using:

CC=cc ../gcc/configure --with-cpu=power4 --prefix=/home/jlquinn

Now during bootstrap I see the following when trying to build the stage 1
compiler.  Using CC=xlc gives the same result:

Unfortunately, I no longer have access to the test box, so I can't verify if it's
working now.

So I am closing this as invalid then as I know David E. was able to bootstrap with XLC and I have not 
seen other reports about this yet.
