     Fix bindist finding gcc on OS X; fixes trac #5397

     $TargetOS_CPP wasn't getting defined in a bindist, which meant the
     code to use gcc-4.2 instead of gcc on OS X wasn't working. Now fixed,
     by moving some of configure.ac's code into the shared aclocal.m4.

  aclocal.m4   |   90 ++++++++++++++++++++++++++++++++++++++++++++++
  configure.ac |  113
