Since AARCH32 extension is not implemented on thunderx family, only
enable build for 64bit.
Due to Linux kernel AF(Admin function) driver dependency, only enable
build for Linux.

Hi Pavan,

Perhaps this patch took more time than it should, but according Jerin's
description the problem is SoC can't run 32bit applications.

Why do you still mention from the kernel driver dependency? It looks like
that dependency is not reason to not compile 32 bit app, am I missing
something?

Since DPDK runs on FreeBSD and Windows and AF driver is absent for those
We are disabling this driver non-Linux compilations too.

Ah, it doesn't only add 'RTE_ARCH_64' requirement, also reduces the support
to Linux, so commit log makes sense. Thanks.
