When compiling dpdk for aarch64 on Centos, I receive compilation error.

I see this in the Centos 1804 distribution.

I haven't tried locally n F28 but I see buildlogs in Fedora28 for dpdk.

I have also reproduced it in qemu-system aarch64 emulation:

uname -a
Linux aarch64-centos7 4.14.0-49.2.2.el7a.aarch64 #1 SMP Sat May 19 18:51:40 BST 2018 aarch64 aarch64 aarch64 GNU/Linux

l3fwd_em.c:245:2: error: #error No vector engine (SSE, NEON, ALTIVEC) available, check your toolchain
 #error No vector engine (SSE, NEON, ALTIVEC) available, check your toolchain

Buildlogs show that dpdk built fine on Fedora 28/29.
