It may be useful for

Alan, can you take a look at it and

http://sources.redhat.com/ml/binutils/2004-04/msg00772.html

They are needed for section group support.

We can add

asection *bfd_get_section_by_name_if
  (bfd *abfd, const char *name,
   bfd_boolean (*func) (bfd *abfd, asection *sect, void *obj),
   void *obj);

It will return the first section named NAME and FUNC returns true.
