Plasma Active on the Nexus 7

I don't know how far Ubuntu got, but I think that cross compiling most likely is not in a useable state yet. For some stuff like kernels, cross compiling works, but I assume that a lot of packages will not be able to cross compile. There are various reasons for that:

* Running built tests during the package build process
* Not prepared for different host and build architectures
* Build-time dependencies not multi-arch ready
