Comment(by leif):
Running `sage -ba` ''explicitly'' is not even necessary upon (true) Cython
upgrades, though we could implement this in `spkg/install`.
We just have to make any Cython file / extension module depend on a
single, distinct file of the Cython distribution (e.g. header) and
preferably make sure this is ''only'' touched when really necessary.
Therefore it would make sense to use a Sage-specific file for such, which
is created and managed by our `spkg-install` for Cython.
People upgrading the Cython package will best know if a complete rebuild
will be necessary, depending on the Cython version found in the current
installation subject to upgrade.
