CI even fails to start:
Error while loading tasks: UNIMPLEMENTED: Dockerfile as CI environment is not yet supported for Arm containers!!(https://cirrus-ci.com/build/4859893270708224).
So this is going to be much more difficult, closing for now...

Okay, so ARM64 builds work!
But ARM32 builds do not run. I tried to play around with this a bit using the Cirrus CI terminal, and I can't make it work. Giving up for now, but here are some notes:
- Error message was
Cannot execute binary file: Exec format error - This indicates that the CPU simply does not support AArch32.
- Indeed, not all ARM64 CPUs are backwards-compatible, but the one the task was running on is a Neoverse N1 and that one has AArch32 support. (https://developer.arm.com/documentation/100616/0301/functional-description/introduction/features)
- We need
CONFIG_COMPATin the kernel, but this was set. - I've seen suggestions to use
setarch linux32 -B [cmd]to run binaries, but this not possible from within unprivileged Docker...
I'll rework this to use only ARM64 then.
