That would risk breaking little endian platforms that failed to define
this. Safest to limit the scope of the change the PPC platforms, where
__LITTLE_ENDIAN__ is a new option, and hence likely to be set correctly.

I would sure like to be able to detect the difference between 'this
option is set to false' and 'this option isn't defined'; is there
something that PPC defines in both cases, and sets to TRUE in one case
and FALSE in the other?
