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.
Fixes: 42ec27a0178a ("sched: enable SSE optimizations in config")

v2 --> v1:
include header file rte_vect.h instead of gcc version check
change __AVX__ to __SSE2__ since all vector function are SSE2 related.
