I made the change before it was apparent that the arch-specific Provides
weren't being generated.  At the point that became clear, it seemed to
make sense to me to fix the Real Problem: as it stands, it is impossible
for downstream packages to articulate the correct Requires.

The change you made results in something that stops generating e-mail,
yet remains incorrect and can in some situations successfully install
something that doesn't work.

I'm afraid it's not glaringly obvious to me how much of a win that is.
