Adding symbols to the hash table
--------------------------------

   The linker proper will call the `_bfd_link_add_symbols' entry point
for each object file or archive which is to be linked (typically these
are the files named on the command line, but some may also come from
the linker script).  The entry point is responsible for examining the
file.  For an object file, BFD must add any relevant symbol information
to the hash table.  For an archive, BFD must determine which elements
of the archive should be used and adding them to the link.

   The a.out version of this entry point is
`NAME(aout,link_add_symbols)'.
