I'm not convinced that there is an issue here. For DPDK compiles
rte_config.h must always be included first, which is why it's included in
the cflags reported by pkg-config. If we do want to move away from having
rte_config as an omnipresent first include, we need to update many DPDK
headers to explicitly include it.
