In this PR we have a situation where we aren't really detecting
weak references vs weak definitions. If one has a weak definition that
binds locally there's no reason not to put out PC relative
relocations.
However if you have a genuine weak reference that is known not to bind
locally it makes very little sense to put out an entry into the
literal pool which doesn't always work with DSOs and shared objects.

condition on the loop looking at previous insns was wrong. Uses of
