It looks somewhat weird that you can enable TUNE_CELL on little
endian systems, so let's disable this option with CPU_LITTLE_ENDIAN.

I first thought that it might be better to make this option depend
on PPC_CELL instead ... but I guess it's a bad idea to depend a
CPU option on a platform option? Alternatively, would it make
sense to make it depend on (GENERIC_CPU || CELL_CPU) instead?

Cause the compiler to optimize for the PPE of the Cell Broadband
Engine. This will make the code run considerably faster on Cell
