As discussed in another thread, the current behaviour is no good when 
running configure outside the source tree root. We should definitely fix 
that (I thought Volker were going to publish a RFR but that didn't 
happen; I'll pick up the ball and submit a RFR). With that in place, the 
behaviour will in principle be that the output is in the current directory.
