Specifically, wrapping the %__find_provides script .

e.g.

%define %__find_provides

... except that according to
https://bugzilla.redhat.com/show_bug.cgi?id=395961 this won't work
because RPM uses an internal dependency generator .

(They're also rude about it in the bug comments).

It looks like, depending on rpm version, a find_provides or
find_requires wrapper must use rpmdeps if it's present and otherwise
fall back to find-provides / find-requires .

Too fiddly for now, that's an idea for later.
