[ovs-dev] [PATCH v1 branch-2.13 1/2] acinclude: Strip out -march provided by DPDK.

DPDK flags may include -march. Forcing -march could be
considered too heavy a requirement when users compile OVS from
source and could override user provided options.
Resolve this by stripping -march from provided DPDK flags.
