Subject: OK, my previous claim for r1015454 was wrong. The new behavior breaks
 old file in many more cases. So activating the new behavior only if the
 USE_RELATIVE_PATH option is given.

(Still, I think we might want to investigate a this trick for files
generated from ui files, and moc files ;-))
