That's supported: you compile on the host and execute on the target. But the 
resulting qmake is for the host, like all the rest of the tools.

Put up with it. If you're going to develop on that device, you should get used 
to slow build times.

It might be possible, but it's not supported. Note that qmake is not the only 
tool: you also need moc, rcc, uic, qdbusxml2cpp, qdbuscpp2xml, etc. There are 
a lot of tools that need to be compiled for the target that the regular Qt 
build would only compile for host machine.
