[meta-intel] [fido][PATCH 09/16] meta-isg: dpdk v1.8: add app makefile patch to enable sysroot setting

[Ong Boon Leong]

DPDK v1.8.0 app Makefile does not support "--sysroot=<path>" option
in LDFLAGS because of Makefile internal logic that always add -Wl, before.
This causes poky GNU linker search path issue for target machine sysroot
usr/lib.

+Subject: [PATCH] dpdk v1.8.0: add --sysroot option within app makefile
+
+Upstream-Status: Inappropriate [configuration]
+
+in DPDK v1.8.0, rte.app.mk has been changed to add -Wl, to
+all items listed under EXTRA_LDFLAGS. It causes --sysroot=
+<path> to not setup correctly when we depends on gcc to setup
+for GNU ld.
