That's how it should be. Every single project out there, except for Qt and 
possibly GCC itself, builds for one single target. Building something for one 
architecture so that it can be run to build another is ungainly and 
unexpected.

Whenever you cross-compile Qt, you end up with tools that can only be run on 
the host. So Qt's cross-compilation mechanism can't be used to build tools 
that can be run on the target platform.
