[ backported from upstream commit 78bfe1666b2063e3fc3fa51e757159f53e1fc779 ]

Expand vector PMD support to aarch32.
Enable i40e PMD by default for armv7 make build.

A patch to enable neon on i40e on meson was tagged for backporting
and included (83ea3b5fa09152da5033f64164f7487296f21f64), but this
required fix to make it build wasn't. Caught when uploading 18.11.10
to Debian and building on armv7.
