Mainly the clashing of build-dependencies. Debian's multi-arch is pretty
good but you still can't generally have two arches worth of complex
dependencies installed at once.

I did originally have one base docker image with all the compilers and
intended to do the dependencies step as part of test-build. However when
running as builders the docker images don't actually have network
ability so couldn't download them.
