Hate to reply to myself, but I'm an idiot as usual. The culprit is in
configure.ac, not in Makefile.am

$CC - -E -mavx </dev/null >/dev/null 2>&1
if [[ $? == "0" ]]; then
  SUPPORTED_FLAGS="$SUPPORTED_FLAGS -mavx"
  AC_MSG_RESULT([$CC supports -mavx])
fi

I need to nail down this stuff to some generally portable subset.

Sorry for the noise,
