[dpdk-dev] [PATCH] lib/librte_sched: Fix compile with gcc 4.3.4

[Michael Qiu]

gcc 4.3.4 does not include "immintrin.h", and will post below error:
    lib/librte_sched/rte_sched.c:56:23: error:
    immintrin.h: No such file or directory

To avoid this issue, a gcc version check is need and a flag to indicate
vector ablility.
