Create Docker containers for easy ARM cross-compilation

This would allow us to more easily build binaries for Raspberry Pi/Odroid Go

Hey, how about we start with a docker container for ubuntu:latest (20.04 as I write this)?

It would be useful to run tests locally without the need for g++-8 - used in CI. They way I see it a script could be used for both the CI and this image's build steps (to reduce duplication and to ensure the 2 envs are the same). Why is this good? Well it would allow people to run tests and all before making a MR (at least on ubuntu - the rest is more complicated...)

Would this be interesting to you? I actually already have the dockerfile since I needed it to understand why some CI step failed.

Sure why not, sounds like something other people might find useful too. And if you already have the Dockerfile, we might as well put it in the repo 🙂
