To be clear, I am not suggesting multiple versions.  The suggestion is
that the old version of mesa overrides the new version and the tests
(and users) get it.

Pretend like we bumped the Epoch.

In this model where version numbers are merely descriptive, other things
would have to change to use the "build serial" and not the ENVR, since
the ENVR is now merely descriptive.

For example, from systemd.spec:

Obsoletes:      upstart < 1.2-7

The 1.2-7 is an ENVR, obviously.  But if you think about it, the
relationship of systemd and upstart here has *nothing* to do with the
upstream version of 1.2, nor the fact that it was the 7th build.

That 1.2-7 is capturing a *point in time* in Fedora (the combination of
packages of systemd and upstart), and a point in time is exactly what a
build serial is.
