On second thought, I'm not quite sure this is the right solution.

It appears the core of the issue is that cmake_qt5 is pulling in the
Qt5LinguistTools cmake from the target sysroot, when it should really
be using the native sysroot.

Does anyone have pointers on the "right" way to handle cmake files and
cross compilation?
