I don't see why handling this on the package management side seems
advisable. We already have a perfectly reasonable distro mechanism for
shipping multiple sonames of a library if we want to do that. We just
try to avoid it wherever possible, because it's not a good idea.

I'm not a genius, but I can't see a way to do this on the package
management side which wouldn't be a horrible hack job.
