The standard SharedObjectEmitter does this (see Defaults.py):

def SharedObjectEmitter(target, source, env):
    for tgt in target:
        tgt.attributes.shared = 1
    return (target, source)

and unfortunately I believe add_emitter is replacing the standard
emitter with yours.  (See Builder.py).  Maybe for now just set
tgt.attributes.shared=1 in your shared emitter.
