If no SSE nor NEON are available the l3fwd should complain loudly to quickly
find out the reason.

It has happened to me once when I've accidently built a GCC without the NEON
support. It was confusing as at first I thought it is a bug... It is not,
there is just missing an error message telling the reason.
