    index: keep index file as long as possible
    
    When generating the INDEX file, we are already building it in a
    temporary file and swap it last minute. make the index target now
    directly depend on the INDEX file generation target.
    Turn that target into a PHONY target so the file is always regenerated
    when someone calls make index.
