rpms and debs of 5.5 and 10.0 galera builds not archived

Unlke the non-galera 5.5 and 10.0 releases, 5.5-galera and 10.0-galera releases don't have RPM (or debs) saved in http://archive.mariadb.org/. They also aren't on the mariadb corp mirror (https://downloads.mariadb.com/files/MariaDB/)

E.g http://archive.mariadb.org/mariadb-galera-10.0.33/ compared to http://archive.mariadb.org/mariadb-10.0.33/

This would make it harder for a deb/rpm user to roll back to a previous version following the
https://mariadb.com/kb/en/library/installing-mariadb-deb-files/#installing-an-older-version or https://mariadb.com/kb/en/library/yum/#adding-the-mariadb-yum-repository instructions fixing to a specific version.

It also makes it hard to take a backtrace and map it to assembly code and the part of line of code that generated the fault (as I was trying to do for MDEV-14888)
