 But note that `-m64` ''does'' appear. I assumed that this and the other
 few compiler invocations that use `-m64` but not `-arch` flags are used at
 build time only and are not installed.

 I confirmed before committing that the universal build worked correctly
 (i.e. other universal ports that use boost that had failed to build before
 the change due to undefined i386 symbols now build successfully).
