We are actively discouraging the use of multilib. we currently have removed it from all active arches except for x86_64 and x86. do you really need it and intend to support it?

Not really, in fact I will be more than happy not having to care about it. I have only tried to get as close to other arches as possible. Should I just update compat and leave biarchs as it is then?

Please just update compat, we will need to get some changes in pungi also for support

Rebased the PR. For pungi - I did not look into it yet but it is on my todo list.
