Marius Storm-Olsen 2e2ad7ec7f Complain if we don't load(qt_module) first
Not having load(qt_module) first in a .pro file which later
does a load(qt_module_config) will likely overwrite
compiler/linker options in the .pro file.

This can be hard to figure out, and wasn't required before
when we used a global .qmake.cache for all modules, since
it 'preloaded' qmodule.pri file for all .pro files.
