Okay, thanks :)!

At least my idea was that there should be a spec file preprocessor,
evaluating the macros that need git context, that would produce valid
rpm spec that will be evaluated by the rpm engine in the end so
everything related to %{dist} generation that is used in those
packages will work unchanged.

A small tweak in those spec files to allow dynamic release bumping could be:

Release: 0.<<dynamic_release>>%{?dist}

or alternatively:

Release: <<dynamic_release prefix=0>>%{?dist} depending on the
implementation of the dynamic_release macro.
