collect2 on AIX drags too many objects from archives ?

 Because we need the tables associated with every "useful" object to be
 registered for exception handling to work, and what is registered is
 currently what collect2 finds while it scans.

 It turns out the double scan actually doesn't work because the eh tables
 of the "useful" object linked in are garbage collected by the native linker
 when they are not referenced, so they are just not there when the
 second scan proceeds :(
