This isn't fun-spoiling, it's a useful reality check.  But if we were
required to get all the way to 100% before we made any progress, then
reproducible builds wouldn't have gotten off the ground at all.

The changes proposed in this bug report are a good step that should
handle a very large proportion of the debian archive.  The fact that
there will remain corners of the archive that need additional work is
fine: we can turn our attention to the remaining 20% once we get 80% of
the buildpaths resolved.
