Add a QMAKE_LFLAGS_EGL and QMAKE_LFLAGS_OPENGL
When you link cross-compiled applications on Linux, the linker needs to
be able to find not just the libraries the application links against
(like libQtGui.so), but the libraries' dependencies. E.g.
examples/widgets/wiggly links against QtGui. QtGui links against
libEGL.so. Therefore, when you link wiggly, the linker has to be able to
find libEGL.so, even though wiggly doesn't use EGL directly.
To facilitate this, -Wl,rpath-link=/path/to/egl needs to be added to
QMAKE_PRL_LIBS in libQtGui.prl and -Wl,rpath-link=/path/to/gl needs to
be added to QMAKE_PRL_LIBS in libQtOpenGL.prl. This only needs to be
done when the EGL/GL libs are not in the default search directories. As
the paths will also change depending on the mkspec, two new variables
have been added: QMAKE_LFLAGS_EGL & QMAKE_LFLAGS_OPENGL. These can be
set in the mkspec and will be added to the relevent prls. E.g.
QMAKE_LFLAGS_EGL += -Wl,-rpath-link=$${QMAKE_LIBDIR_EGL}
QMAKE_LFLAGS_OPENGL += -Wl,-rpath-link=$${QMAKE_LIBDIR_OPENGL}
