Multi-profile Emacs should be supported, but this also breaks on
foreign distros with foreign distro ELPA.  Again, hacking variables is
not the solution (and even if it was, it'd be better to patch the emacs
default value, not that this is a good idea either).

Generating our own -pkg.el should work, still waiting for Maxim or Arun
on a statement as to why we exclude it.

*Always* generating a -pkg.el (disregarding the upstream one if it
exists) might further be a reasonable thing to do if we decide, that
those -pkg.el files are useful.

Leo
