[oe] [meta-qt5] Building and running issues on Raspberry Pi

It's not possible to have hardware-accelerated QT on the raspberry pi when 
you are running an X11 environment, therefore I want to use eglfs 
directly.

The raspberry pi doesn't have a mali graphics core, AFAIK.

Nevertheless, applying your patch gives me an error while compiling.

"
[...]/qeglfshooks_stub.cpp: In member function 'virtual void* 
QEglFSHooks::createNativeWindow(QPlatformWindow*, const QSize&, const 
QSurfaceFormat&)':
[...]/qeglfshooks_stub.cpp:256:38: error: variable 
'QEglFSHooks::createNativeWindow(QPlatformWindow*, const QSize&, const 
QSurfaceFormat&)::mali_native_window native_window' has initializer but 
incomplete type
     static struct mali_native_window native_window = {
                                      ^
[...]/qeglfshooks_stub.cpp:261:1: warning: control reaches end of non-void 
function [-Wreturn-type]
 }
 ^
make[4]: *** [.obj/qeglfshooks_stub.o] Error 1
"

Any suggestions?
