In addition to what Johannes replied about cross-builds having issues
in general right now, we know a lot of people are running into this
and are tracking it in
https://salsa.debian.org/salsa-ci-team/pipeline/-/issues/374

While Salsa CI can't fix the fundamental cross-build issue, we should
try to have better error messages and better documentation on why
cross-builds are allowed to fail by default so people are not left
wondering..
