Don't misunderstand Seth's list. The Provides are necessary and must not
be stripped, because external packages may require them. The Requires
in a pkg could be stripped if it's the same pkg that Provides the
needed things.

The "thunderbird" pkg contains a "find-external-requires" script which
does the thing that's proposed here. It ought to be rpmbuild, though,
that does this for all pkgs.
