Right, but what about consistency in BR? if we do all the job for
having a full relocatable SDK, why should we keep this symlink an
absolute one?
Also, one of my tests in the relocatable SDK work is moving around the
whole output directory; so I need this patch in this case. Maybe this
is not a valid case?
