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. -- Alex Bennée
