The problem is that just pointing to a qmake binary is not enough as Creator
runs a couple of sanity checks to ensure the associated Qt build is "usable".
This is simply "too much" in this particular case.

It is possible to trick Creator into believing that "all is well" by creating 
a dummy libQtCore.so matching the target architecture and copying parts
of a real Qt's mkspec directory, but that's clearly a hack.

However, it shows that the setup works, and I think it's a use case that's
worth supporting properly. It seems to be rather common to share code
between, say, a Qt based visualization application running on a desktop 
and some data acquisition process running on an embedded system 
without Qt. The request comes up  regularly, from different parties.
