[Mageia-sysadm] Mass rebuild

[Pascal Terjan]

I was thinking about it tonight

Rebuilding everything takes 1 week building one package at a time

If we temporarily added sucuk and rabbit as build nodes (twice each
like the two other) and submitted all packages, it would take less
than 24h.

The hardest part being to bump the release in all specs (not sure how
many have some strange way to set the release)
