Hmm, we already have a problem with the travis CI bulds that we're stuck
on outdated Ubuntu.

We also already have a set of dockerfiles in tests/docker/ for various
build configs maintaniers are expected to use.

Both Travis and GitLab CI are capable of using docker images.

What's blocking us in both Travis & GitLab cases is that we're not
publishing the docker images for QEMU yet. If we can get that working,
then all the CI can use pre-build docker images, saving the time
for downloading the same DPKG files each time, as the docker images
would be cached by the CI system IIUC.

The other reason I think it would be desirable is to get more consistency
between the various build systems used in QEMU.

Regards,
Daniel
