Ah, I see.  Can we just move over tmu2 to use epoxy too, then drop the
deps handled by epoxy?  So we don't need a new CONFIG_EGL option ...

Ideally tmu2 should also be moved from talking to glx directly to use
the (egl-based) qemu opengl interfaces.  That'll be a bit more work
though as tmu2 needs be ported to the modern opengl desktop interfaces
then ...

cheers,
