  On OSX the output of "uname -m" always reflects the 32-bit architecture
  for the machine ("i386" or "ppc"), even if the executable is
  64-bit.

  This patchs ensures that the distutils platform architecture
  represents the architecture for the executable when running a
  64-bit only executable on OSX.
