Ah yes.  When this IF runs we already checked that we are building a
hurd system; this adds two lines leading up to the above snippet

  (if (operating-system-hurd os)
      (let* ((mach (operating-system-kernel os))
             (mach (if (%current-target-system)

...but that means that this last IF is maybe unnecessarily implicit and
only really makes sense by adding/remembering that context.  Changed it
to

             (mach (if (and=> (%current-target-system) hurd-triplet?)

I guess that's friendlier?

Yes, I've added a comment

                     ;; TODO: cross-libc has extra patches for the Hurd;
                     ;; remove in next rebuild cycle
                     (cross-libc target))

I have now 8 squash! commits; I'll be resetting wip-hurd-vm just once
more before merging, after checking in with Ludovic and re-running some
tests.

Really looking forward to seeing a Guix Hurd VM hookup-up in bayfront
and really start building a Hurd system, mabye we'll see some more
people join in.  I think that should be (almost?) possible after
merging, right?

Greetings, Janneke
