This guarantees for the package feeds that
the mk files will always be available for all packages.

Will need to see about external-feed Python packages
a bit later.

Unfortunately python-cryptography (after version 2.0.<something>)
decided to replace `pyasn1` with `asn1crypto`.

Unfortunately `pyasn1` is needed for another package,
so it can't be dropped just yet.
Not sure if dropping it would bother people.
