[PATCH 03/94] sys-libs/glibc: prepare for GNU Hurd

We need to DEPEND on sys-kernel/gnumach for GNU Hurd (*-gnu, but not
*-linux-gnu) but with a slight snag in that we need -headers-only, as
gnumach[headers-only] is the very initial build we do w/o GNU MIG.

We may wish to pull in some Debian-local [0] patches to workaround issues
with CPython but not tried that yet. Hurd support is in upstream glibc but
Debian has some patches to stub interfaces or add hacks to make packages
work which aren't suitable for upstream. But a surprising amount works without
those.
