Invalid configuration `gibberish': > machine `gibberish' not recognized" this is coming from the config project [1]. it is responsible for parsing the specified tuple to see if it resembles something reasonable. giving it gibberish is not reasonable, so it aborts. but a bare cpu name like you showed at the top is valid syntax. it just doesn't expand the way you're expecting.
