# "wc" and "cksum" can make use of AVX, but since the kernel has added a
# mitigation that makes AVX seem to be available when it really isn't,
# it is not reliable. Even the author of this wc optimization questioned
# how useful it really was... and for us, it isn't worth it to have by
# default. But feel free to enable/recompile if you like.
# The upstream suggestion to use the GLIBC_TUNABLES to disable this would
# be system-wide, so that's just a no-go.
