Issue #15782: Prevent compile errors of OS X Carbon modules _Fm, _Qd, and
_Qdoffs when compiling with an SDK of 10.7 or later.  The OS X APIs they
wrap have long been deprecated and have now been removed with 10.7.
These modules were already empty for 64-bit builds and have been removed
in Python 3.  (Original patch by Ronald Oussoren.)
