Re: Followup to gcc-3 bugreport on Hurd

I fixed the conditionals in sysdeps/mach/configure so that
libc_cv_gcc_unwind_find_fde is yes in the cases where a pre-2.2.5 ABI is
supported and no in the cases where it's not.

This lets me build the compatible case (i.e. without --enable-libio
or --enable-oldest-abi, so you get libc_cv_gcc_unwind_find_fde=yes).

However, when building the libc_cv_gcc_unwind_find_fde=no case, I get some
multiple definition errors unless I remove the `-u __register_frame'
argument from the link command.  Since I'm using the Red Hat 7.1 compiler
(2.96-85), I don't know if this is supposed to work or not.  If it works
for gcc-3.1, then I guess I don't care about this RH compiler.
