    This adds the 'magic' rules that take care of subdirectories.
    The subdirectory makefiles in the source tree are not complete; they
    only define some variables (listed in nested-vars) according to the
    configuration.
    
    The magic rules descend into subdirectory makefiles and gather the
    evaluated values of those variables.  The values from all subdirectories
    are joined together, each prefixed with the subdirectory name, and used
    by the "real" makefiles.
