If anyone knows how to make rpm to evaluate %(...) immediately and not
at every appearance of rhel/fedora, that would be really cool.
It looks like %{lua: expression} is the trick to do an immediate
evaluation; my problem is that I don't know the appropriate lua
expression to replace your sed script.

This looks reasonable as is, but like you said, it would be nicer to
compute it once.
