A72 is just _an_ implementation of armv8. Not ARMv8 specification
itself. By specification it is NUMA capable and there are NUMA
implementation too.

It just an build time dependency. Right? If you feed the libnuma package,
it will NON NUMA as well. Right? ARM64 libnuma package is already
available for major distributions.
My point is, I don't want to make arm64 generic config an exceptional case,
If DPDK common config creates libnuma dependency then there is no reason
for arm64 not have it. It is same for x86 and powerpc, non numa systems
too. Right?

On the same note, arm64-armv8a-linuxapp-gcc used by other vendors for Server machines
with NUMA and if want to keep creating new targets there is no end to it.
How hard is to install libnuma on VM? There is already package for it.
