And just to prove that point: when the staging dir is removed from the
include path, that file compiles fine. That is, after symlinking the
QtCore directory to somewhere else in the include path, otherwise the Qt
includes can't be found. Another solution is to replace the -I with
-idirafter, so the system includes come first.
The reason that the staging dir has to be included is because that's
the only place where you can find the core Qt libraries.
The funny thing is that Qt is smart enough to link with the libraries
in host/usr/lib and install the executables in host/usr/bin...
