yes it is.

I don't have any GL/EGL lib on my paths.

the issue is not is the QtGui, but in the explicit "-lGL" that is passed to
the link command.
I simulated the cross-compilation for my x86_64 machine with the following
./configure -opensource -confirm-license -no-eglfs -no-xcb -directfb
-xplatform linux-g++-64 \
-prefix /home/rahmanih/qt-5.0.0 -no-opengl -no-xrender
-no-xkb -no-xinerama -no-xshape \
-no-xvideo -no-xsync -no-xinput -no-xinput2 -no-egl
-no-xcursor -no-xfixes -no-xrandr
and it's the same in the "qtbase/src/widgets/Makefile"
LIBS = $(SUBLIBS)
