ccc: Allow downstream tools to be aware of final output name.
 - This is a hack to allow the Darwin linker to get -final_output when
   doing universal builds; the mechanism should be generalized.

 - Handle multiple redundant -arch arguments correctly.

 - Forward -arch_multiple and -final_output to gcc when necessary.

 - Simplified implementation of derived gcc tools.
