I think it would be a good idea to define a backend function to process
each plt reloc.  Given a pointer to the plt section, and a pointer to
the reloc, it could return the value of the sym or -1 if the reloc
should be ignored.  That should be general enough to work even with
something like the sparc plt, and you won't need plt_entry_size or
reserved_plt_size.
