With this comment I suspect they have feature-detection code, but
include this in case someone is building with a very old compiler that
can't do some shiny AVX thing.

So, if the default compiler you have works with it without
needing to specify any additional compiler flags and no use of
-march=native or -mcpu=veryshiny, I would ignore this comment.
