    Checkpointing some makefile simplifications that I attempted.
    
    This is not in a working state yet, as we are trying to build
    something that goes into the build/ dir but it is not yet
    created. Not sure how to add dependency tracking properly.
    
    Btw., Ian is working in this area on the master branch so
    there will be a bunch of conflicts anyway :-(
