Hi Guys,

  I am checking in the patch below to handle the situation where the
  plugin handler is asked to canonicalize a weak symbol of an unknown
  type.  This situation actually occurred in real life due to a bug in
  the LTO plugin, and that bug was made worse by the code in the handler
  not detecting it and leaving the section pointer set to NULL.

Cheers
  Nick
