This sounds like the cases where we have to build the tools we need.
There's an example in .travis.yml for QEMU already, and we use
https://gitlab.denx.de/u-boot/gitlab-ci-runner/ for Azure/GitLab.
Testing those with your own container does require setting up an Azure
account or using your own GitLab + runner.

That said, if you unit test things and are confident it won't blow up
when I test it, that can be good enough.  Thanks!
