This is a tracking bug for Change: Prevent from building RPM packages providing python3dist(...) = 0
For more details, see: https://fedoraproject.org/wiki/Changes/Prevent-Providing-python3dist(pkg)%3D0

It sometimes happens that Python packages succeed to build as RPM with incorrect version metadata.
They generate a wrong provide in format python3dist(...) = 0 and python3.Xdist(...) = 0.
While version 0 (or equal versions like 0.0 or 0.0.0) is probably technically valid, in most cases this indicates a packaging error. 
We propose to prevent this error from happening by explicitly failing the RPM build instead of generating such provides.
