  Issue #7117 (backport py3k float repr) continued:
   - add double endianness detection to configure script
   - add configure-time check to see whether we can use inline
     assembly to get and set x87 control word in configure script
   - add functions to get and set x87 control word in Python/pymath.c
   - add pyport.h logic to determine whether it's safe to use the
     short float repr or not
