I don't know about this patch in particular; however, what you describe above (same distro same version different arch) is certainly useful, especially for embedded devices for which vpp is a target. We do this. Is VPP looking to remove or not support this type of cross compilation? Perhaps this is already known, but for ubuntu/debian it supports installing multiple architectures libraries (shared or otherwise) for x-compile support using dpkg --add-architecture (see https://wiki.debian.org/Multiarch/HOWTO). Openwrt/build-root use a different mechanism x-compiling everything from source I believe.
