Change endian.h so that when a kernel is compiled without I386_CPU, and
with one of the following (I486_CPU,I586_CPU,I686_CPU) so it can take
advantage of the very quick bswap insn. This keeps LKMs from being
built to take advantage of the insn, but also makes sure that the LKMs
can be run on all CPUs. (The LKMs don't pick up the CPU options :-( ).
