  This has been only build-tested for now, on a native ppc64el POWER8E
machine running Debian sid.

The build box cannot be used to run DPDK as it doesn't have supported
NICs and root access. Would be great if someone could run-test it, but
at this point I think build support is enough to get started.

Checked on ppc64, the build process is successful.

This contradicts the statement above in config/meson.build where you state
that ppc64 doesn't support "-march=native"?

Yeah I copy-pasted the arm file to get started, but it doesn't seem to
me march_opt is used anywhere else other than in the x86 specific file,
so I've dropped that line in v2
