algos.c is compiled on all platforms, so you'll need to ifdef that x86
section where SSSE3 is no longer guarding it. The pattern in the rest
of the file, if you want to follow it, is "#if defined(__x86_64__) &&
!defined(__arch_um__)". That seems ugly and like there are better
ways, but in the interest of uniformity and a lack of desire to
rewrite all the raid6 code, I went with that in this cleanup:
