Great! Please note that POWER can be 32- or 64-bit, big- or
little-endian. All four combinations are possible, depending on the
operating system. So we need actual detection of word size and
endianness, like we had in "make generic" before. Unfortunately, magnum
dropped that when adding autoconf support, but I think we need to
reintroduce it.

You'll need to post benchmarks once you've added some basic SIMD
support. Right now, I guess you got SIMD for some DES-based formats only.
