I reviewed this patch (with Joseph's additional change to not duplicate
the DEFAULT_LIBC definition in certain cases), and it appears correct to

I also tested this one instead of my original patch, and successfully
built GCC natively on i686 GNU/Hurd.

s%DEFAULT_LIBC and %% as per your follow-up email.
