When compiling DPDK (and any DPDK app), gcc may generate Intel® AVX
instructions, even when the processor does not support Intel® AVX.

Implication:
Any DPDK app might crash while starting up.

Resolution/Workaround:
Either compile using icc or set EXTRA_CFLAGS='-O3' prior to compilation.

Affected Environment/Platform:
Platforms which processor does not support Intel® AVX.

Driver/Module:
Environment Abstraction Layer (EAL).
