[13/21] Fix counting of line-number entries

[Nick Clifton]

Hi Richard,

> bfd/
> 	* libcoff-in.h (xcoff_tdata): Add a lineno_counts field.
> 	* libcoff.h: Regenerate.
> 	* xcofflink.c (xcoff_link_add_symbols): Record per-symbol
> 	line-number counts in the bfd's lineno_counts field.
> 	Don't keep per-csect line-number counts.
> 	(xcoff_sweep): Don't update per-csect line-number counts.
> 	(bfd_xcoff_size_dynamic_sections): Count the number of line-number
> 	entries in each output section.
> 	(xcoff_link_input_bfd): Get the number of line numbers from
> 	the bfd's lineno_counts field, rather than recalculating it
> 	from scratch.  Fix the range check when updating C_BINCL and
> 	C_EINCL symbols.
> 	(_bfd_xcoff_bfd_final_link): Don't count the output line numbers
> 	here.  Don't expect csects to have line-number counts.
