Gernerate dpdk config out of target specific files
Gernerate dpdk config out of target specific files

DPDK 16.04 introduced new config parameter RTE_ARCH_X86
which was missing in the dpdk/Makefile

That caused issues with virtio devices on older kernels
(observed on 3.13.0).

This patch changes the source of generated config so
it will also include all defines in config/defconfig_TARGET
file.
