I fixed it in this branch, could you please test it? Thanks.

The modification compiles correctly, but the reason for this failure is that the header file rte_vect.h is not included. Would it be more appropriate to include this header file, even though currently arm does not support 512-bit wide SIMDs?

could you submit a pull-request to fix it? I don't have a ARM env right now.
