Ugh.,

Just make it little-endian only.

The _worst_ thing to do is to make it some kind of "native-endian",
because then you have to deal with cross building issues etc.

But using a __le32 type and just doing "le32_to_cpu()" is trivial and
optimal - not just because everybody relevant is LE anyway, but simply
because even if you _aren't_ LE, an unconditional byte swap is better
than a conditional native access.
