I have enabled arm64, armhf and ppc64el builds in both repositories, added the Yakkety series to all packages and (hopefully) built everything for arm64, armhf and ppc64el within both PPAs.
There were some failures, most notably x2goclient in the nightly repo for Trusty for arm64. x2gomatebindings is in dependency wait mode for arm64 and armhf for Trusty and arm64 for Precise. Everything else seems to have worked fine so far, at least compilation-wise.
