Please define ARCH_CPU_LITTLE_ENDIAN here, repeated for the
three supported CPUs:

#define ARCH_CPU_LITTLE_ENDIAN 1
#undef ARCH_CPU_BIG_ENDIAN

The #undef is not necessary and merely serves to document
what the opposite macro is, since we don't support any
big-endian architecture right now.

Then we don't need the separate block on lines 111-117.

Done.
