[meta-intel] [master & fido][PATCH 10/16] meta-isg: dpdk v1.8: introduce target machine selection for DPDK.

[Ong Boon Leong]

DPDK default config set the TARGET machine type to native which is
incorrect. The SDK assumes that the DPDK package is built and installed
natively. So, to support cross-compilation uses, we add DPDK_TARGET_MACH
option here. This variable should be defined at either dpdk bb or bbappend
file.

+Subject: [PATCH] DPDK: defconfig: add selectable RTE_MACHINE option
+
+In order to make sure that DPDK build environment config can handle the
+package being built on different build machine for different target machine
+which will have different x86 architecture intrinsics than the build machine,
+we introduce DPDK_TARGET_MACH to be tunable from dpdk recipe. The machine
+type can be under mk/machine folder.
