If we revert that commit, we will bring back bug#62734, which to me
sounds like a similarly serious, perhaps even more serious, issue,
don't you agree?  So I think maybe we need to amend that commit with
something that takes care of the particular situation reported here.
Specifically, it seems we need to detect the situation where a package
has no autoloads at all, and then produce the minimal autoloads file
that such packages expect.
