configure -nomake accepts anything as argument, doesn't warn and may produce bad builds

t4id: 247073

When configuring Qt with "-nomake part" with part being one of

, libQtUiTools.a is built; however, when configuring with "-nomake part1,part2" with part1 and part2 being any of the above, libQtUiTools.a is not built.
If it is not possible to give a command separated list to "-nomake", there should a warning be issued to pass only one argument at a time to "-nomake".
