The libgcc2.s file has obvious problems.

(null) isn't a valid register name.  It looks like your C library prints 
null pointers as "(null)".

I can build a x86-linux hosted powerpc-elf cross compiler which works 
OK.  I didn't use any configure options or set any environment flags.

It appears that something got miscompiled on your end.  I suggest that 
you try debugging it.  Put a break point in print_operand and step 
through it.  The error is probably much earlier though.  I suspect that 
the reg_names array is not getting initialized correctly.  It gets 
initialized with a constant initializer in regclass.c.  Maybe it is 
getting clobbered at some point while the compiler is running.
