Yes; that worked and it simplifies things a lot.  So, wip-hurd is using
guile-2 and gcc-5 now.  Using gcc-5 allowed me to remove the puzzling
gcc-boot0 patch.

Just reset wip-hurd again; it was fully up to date with core-utils when
I started building the bootstrap-tarballs... Rebasing right now to
verify for a new round ;-)
