Sorry for the delay, but this is awesome work!  I=E2=80=99m impressed that =
you
got it working in so little time.

I=E2=80=99m not offering a full review yet.  I think it=E2=80=99s an additi=
onal
incentive to finally merge the remaining bits from wip-hurd.  ;-)

My main concern is the complexity of the cross-base stuff.  Why is
=E2=80=98cross-gcc-core=E2=80=99 needed, for instance?  It=E2=80=99s probab=
ly inevitable for the
complexity to be proportional to the number of target libcs, but I think
we should start thinking about how to master this complexity by
factoring/abstracting things a bit.

A cosmetic comment: I=E2=80=99d put the MinGW packages in a separate module.

I think portability patches should be (1) submitted upstream ;-), and
(2) applied unconditionally on all architectures (assuming they do not
make any difference on the other architectures.)

=E2=80=98core-updates=E2=80=99 is open, so now is a good time to add patche=
s to the
toolchain packages, for instance.  :-)

Thanks!

Ludo=E2=80=99.
