Prior work:
We happen to be using Java 11 + Mandrel 22.0.0.2 on Ubuntu, so I found it easier to get the vanilla Mandrel distribution than to fork any of those. The https://github.com/quarkusio/quarkus-images Quarkus images use build infra that's very far from ours.
Emulation as in https://github.com/qiot-project/qiot-ubi-multiarch-builder is interesting, but given our current 10-15 minutes build time on the host's native platform I think the way forward is to use both amd64 and arm64 build nodes.
