Indeed, building inside the L1 guest seems like a waste of CPU time when
the bits are already built natively in the flights build-* jobs.

Even if it was desired for some reason then the right approach would be
to point ts-{xen,linux}-build{,-prep} at the L1 guest, not to duplicate
the functionality in ts-debian-hvm-install (see my earlier reply to
Robert regarding what ts-debian-hvm-install's scope should be).
