lomiri-push-service's build tests [fail on s390x](https://buildd.debian.org/status/package.php?p=lomiri-push-service) s390x is the only Debian release architecture that is big-endian. There are some Debian "ports" [architectures](https://wiki.debian.org/ArchitectureSpecificsMemo) that are big-endian, but we don't have a build attempt on those architectures for other reasons. The murmor3 test is old, from 2011. Ubuntu completely skipping running tests for the predecessor `ubuntu-push` project. Before that, I did see a successful s390x build but in the build I looked at, it looked like dh_auto_test wasn't actually running for s390x. I don't think we care much about s390x for Lomiri's use cases. I'm filing this bug for reference.
