[OE-core] qt embedded enable plugin-gfx-powervr

[Stefano]

Ok, now i'm trying to build the plugin-gfx-powervr but i need a little 
help with editing the recipes.

For my test i'm editing the qt4.inc with this lines:

QT_GLFLAGS ?= "-opengl es2 -depths 16,24,32 -plugin-gfx-powervr"

and i add at the end of line of QT_CONFIG_FLAGS
  "-DQT_NO_QWS_CURSOR \
   -DQT_WS_CLIENTLIT"

so i start the building with:
MACHINE=beagleboard ./oebb.sh bitbake qt4-embedded

But the build blocks on this error:
pvrqwswegl.c:42:30: fatal error: GLES/eglplatform.h: No such file or 
directory

So i apply these patches from 
https://github.com/prabindh/qt-configs/tree/master/qt4.8 and build is 
finish correclty.
Problem #1 i see the rm_work delete the folder of qt library but i need 
that for cross-compile with qt-creator my program.
I see the new library is installed in 
/tmp.../sysroot/beagleboard/usr/lib so i copy and paste on my sdcard in 
the same position.
And i run qdemo -qws -display powervr and i get:

Problem #2
QLibraryPrivate::loadPlugin failed on 
"/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so" : "Cannot load 
library /usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: 
(/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: undefined symbol: 
_ZNK16QWSWindowSurface12directRegionEv)"
"Cannot load library 
/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: 
(/usr/lib/qtopia/plugins/gfxdrivers/libqgfxpvregl.so: undefined symbol: 
_ZNK16QWSWindowSurface12directRegionEv)"  could not load

Anybody have some info to solve the problem?
Thank's
