[dpdk-dev] [PATCH 1/3] examples/distributor: fix build for non-x86 arch

[Thomas Monjalon]

_mm_prefetch is defined only in x86 compilers.
rte_prefetch functions are defined in EAL for each arch,
and must be preferred over compiler intrinsics.

Fixes: 07db4a975094 ("examples/distributor: new sample app")
