When I build an image with QT5 using meta-arago, qtbase fails with a lot
of error messages.
Some errors:

Googling indicates that this is because:
"If -no-opengl is specified and OpenGL development files are
installed, the error does occur."
If I clean out qtbase, and then continue build, it will complete.
$ bitbase -c cleansstate qtbase
$ bitbake <image>
My guess is that during configuration, OpenGL cannot be found, but it is
there during compile.
There seems to be a dependency error (libgles-omap3?).
