ext:*environment-list* is O(n); it sucks and is totally clunky, and
not case-preserving. Kill it with fire.

It doesn't make sense for the normal tarball to contain asdf but not
some module required for asdf.

Maybe add a canary test for your tarballs, that makes sure you can run
some trivial asdf program?
