PATCH Qt applications fail to build on ARM using g++ -Werror -Wold-style-cast

Attempted to build an application on ARM using g++ -Werror -Wold-style-cast.

Expected to see:
Successful compile without errors

Got instead:
Compile failed due to C-style pointer casts in Qt headers specific to the ARM architecture

More details:
This patch resolves the problem:
