I view these more like build artifacts since the messages in them are
really only relevant to a specific build instance, so I would probably
clean them up with 'clean' over 'mrproper' / 'distclean'. But if they are in
.gitignore, I don't think it matters too much though, but it does feel
like they should be cleaned up with at least 'distclean'.
