I've been looking at this for the linux-user stuff. I suspect we want
another class of images (DOCKER_SRC_BUILD_IMAGES?) so we can decide if
they get built. It's probably time we start moving the dockerfiles into
appropriate subdirs rather than treating them all as one monolithic set.

Have you looked at:

  https://docs.docker.com/develop/develop-images/multistage-build/

It would be nice if we could split the build from the final artefact
image. That way the interim can be thrown away after a successful build.
