GCC thinks target atom doesn't support SSE4.2 and SSE4 is now part of
minimum requirements for DPDK on x86. So there are compiling errors when
cross-compiling for target atom. And in fact, the atom supports SSE4 now.
This patch fixes this issue.
Fixes: 5ea4d4688dce ("net/ixgbe: remove fallback code for x86 non-SSE4")
