Really, I don't think that making what is a legitimate noarch package, such as 
fedora-release or generic-release (keep in mind this would affect both, and 
would be an extreme change affecting Remixes) is the way to go here. We can 
already test against architectures using `%ifarch`, and sure that's not clean 
when you're testing against a *range* of architectures, but it's definitely 
better than adding additional complexity to a noarch package.

If anything, perhaps a virtual package, as suggested by others in this thread, 
would be the way to go.
