+ 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.
