Package: x2goserver, mate binding etc. in debian jessie main
In the jessie debian repo, the armhf architecture is incomplete: there is no x2goserver (and others are missing too) in http://packages.x2go.org/debian/dists/jessie/main/binary-armhf/
I would reckon the packages in jessie/main should be without missing dependencies.
However, generally you can compile for the armhf arch, as it is being proved by the ubuntu main stable x2go trusty ppa: https://launchpad.net/~x2go/+archive/ubuntu/stable/+files/x2goserver_4.0.1.1...
