See lines 152 and 153 of gpu-viv-bin-mx6q.inc. If something needs
libEGL.so then this probably needs to be changed to how libgles and
libgles2 are done. It would be nice to document exactly where the
dependency is though so that we know when we can remove the hack once
it is fixed.

I can't see the dependency from inspection. What's the exact error message?
