Workaround

vim /buildarea2/lyang0/benchmark/ovdk/bitbake_build/tmp/sysroots/intel-xeon-core/DPDK/mk/rte.vars.mk
add: CC = x86-64-wrswrap-linux-gnu-gcc

Steps to Reproduce

/buildarea2/lyang0/wrlinux-x/wrlinux/configure --enable-board=intel-xeon-core --enable-rootfs=ovp-kvm --enable-addons=wr-ovp --enable-parallel-pkgbuilds=20 --enable-jobs=20 --with-template=feature/intel-dpdk,feature/dpdk-vswitch --with-layer=wr-intel-support

build error will happen "cc1: error: unrecognized command line option "-msse4.2"
but it uses the build servers's gcc, our gcc support this flag, see workaround
