There's a bunch of issues with cross compiling a lot of things,
partially around a bunch of the things that run around the actual
composing. The way OBS does that is by running those bits in a qemu
emulated. It's quite messy and it would need a bunch of development.
We're much closer to getting ARMv7 on aarch64 VMs running and that
would be more suitable for all involved.
