Hmm maybe - to be honest the naming is at variance with what it actually
indicates. They are perfectly usable images (they are used for cross
compiling tests) but they are not usable for building QEMU itself hence
use the DOCKER_PARTIAL_IMAGES field to stop them being expanded in the
test runs.

If I had my time again....
