-# option, target, which comes from the --target options, and undefs, which is
-# an argument that isn't an option (cuz it doesn't start with --). Ie:
-# configure --host HOST --target TARGET --opt1 UNDEFS --opt2 --opt3 ...

-# undefs at the same time. After that, we do defaulting. The host defaults to
-# undefs. Ie:
-# configure --target TARGET --opt1 HOST --opt2
-#
-# If there are no undefs, the host defaults to the current host (as determined
-# by config.guess).
-#
-# Target defaults to undefs. If undefs wasn't specified, then it defaults to
-# host.
