James Antill added this text re: when Requires should *not* be
arch-specific:

        A package has a Build-Requires on a specific arch. library
        (because rpmbuild evaluates the %{_isa} at .src.rpm buildtime,
        and not at .src.rpm => .arch.rpm build time).

I don't understand what this is saying.  Can anyone put this in more
lucid terms?
