    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.
