   What we're trying to do here is allocate a toc section (early), and attach

   written out before all files have been processed. This code allocates
   a toc section for every file, and records the last one seen. There are
   at least two problems with this approach:
   1. We allocate whole bunches of toc sections that are ignored, but at
      at least we will not allocate a toc if no .toc is present.
   2. It's not clear to me that being the last bfd read necessarily means
      that you are the last bfd closed.
   3. Doing it on a "swap in" hook depends on when the "swap in" is called,
      and how often, etc. It's not clear to me that there isn't a hole here.
