But check out the remaining 2%: It's firmware and data files that
should not carry a disttag (and they should not even be rebuilt at
all).

Same goes for the disttag itself and when I brought up this request
some years ago to have an appendable "releasesuffix" macro for rpm the
god of rpm loudly laughed and looked away ;)

See for example (no rpm god involved)

http://www.redhat.com/archives/fedora-packaging/2005-February/msg00116.html

| 
| rpmbuild -bs --define 'releasesuffix .at' foo.spec
| 
| produces the distro agnostic foo-1.2.3-4.at.src.rpm
| 
| rpmbuild --rebuild --define 'releasesuffix rhel4.at'
| foo-1.2.3-4.at.src.rpm
| 
| produces foo-1.2.3-4.rhel4.at.i386.rpm
| 
| As a side effect the releasesuffix macro/header tag can be used both
| for disttags as well as for repotags, the latter being just a mark of
| origin.
