[RFC] Correction for files with SBSS sections and no BSS sections

[Paul Hilfinger]

We have noted cases (especially on our Tru64 5.1 installations) in which
an executable contains an SBSS section, but no BSS section.  This results in
the messages

  gdb-internal-error: Section index is uninitialized

  An internal GDB error was detected.  This may make make further
  debugging unreliable.  Continue this debugging session? (y or n) 

etc.  I propose the following fix, but I'm not sure I understand all the 
implications.  Comments?

	* symfile.c (default_symfile_offsets): Allow for case of files 
	containing an SBSS section without a BSS section.
