I remember having this issue on Ubuntu 16.04 as well. It's fixed in DPDK 16.07 (there's an -rc5 version out already) but if I remember correctly I made a local patch for DPDK 16.04 to keep going. I _think_ it was this patch, but I'm not sure, you may want to try it:

Dear DPDK Users,
I successfully built the mlx5 on Ubuntu 14.04 before, but when I tried to build it on Ubuntu 16.04, I encountered these compilation errors. The kernel version is 4.4.0-31-generic. Build command: make install T=T=x86_64-native-linuxapp-gcc
