It's not normally that bad.  Old packages exist in snapshot.d.o.  In
the case of util-linux that the original poster talks about, the old
version of util-linux is still in the chroots of the buildd, its just
that wanna-build no longer knows about that version so does not offer
util-linux for building, so one has to manually schedule a build and
binary upload.

The situation is different for boot strapping a new architecture.
There are quite a number of circular build-dependencies and one breaks
the circle with a variety of techniques, one of which is cross-building.
