[AVR] Module cpp could not be loaded after upgrading to QtC4.5

Now, after update from QtC 4.4.1 (QBS 1.9.1) to QtC 4.5 (QBS 1.10) it is impossible to build any application, based on AVR GCC toolchain (please see a previous related issue --QBS-1203--).

E.g. even trying to open the 'helloworld-minimal' example from the QtC leads to message:

"C:\Qt-meta\Tools\QtCreator\share\qtcreator\qbs\share\qbs\imports\qbs\base\CppApplication.qbs:34: warning: Module cpp could not be loaded."

"E:\git\ng\123\qbs-git\qbs\examples\helloworld-minimal\hello.qbs:53: warning: Product 'HelloWorld-minimal' had errors and was disabled."

Please see screenshoots and an archive qbs.zip with created profiles for 1.9.1 && 1.10.
