[PATCH] bpf/xdp: disable on 32bit x86

[PATCH] bpf/xdp: disable on 32bit x86

[luca.boccassi]

From: Luca Boccassi <bluca@debian.org>

As per Intel, this is not supported, and the librte-bpf test fails on 32bit x86
kernels, so disable the library and the pmd.

Recheck-request: iol-compile-amd64-testing

The DPDK Community Lab updated to the latest Alpine image yesterday, which
resulted in all Alpine builds failing. The failure is unrelated to your
patch, and this recheck should remove the fail on Patchwork, as we have
disabled Alpine testing for now.
