    metadata: interate over source packages when generating Makefile
    
    All build dependencies are between source packages. Interating over source
    rather than binary packages simplifies parts of the code and prepares
    further improvement.
    
    As a side effect, this changes the implicit default variant of a few
    packages (the first defined is used now instead of the lexicographically
    first).
