    Explicitly use object-files in library-generation
    The macro $? only evaluates to the list of prerequisites that are
    newer than the current target. While this incidentally works when
    simply compiling, this leads to the library-files only including
    the changed .o-file (and nothing else!) when a single source file
    has been changed.
    This is easily fixed by explicitly listing the object-files.
