bfd/Changelog:

	* libbfd-in.h (_bfd_link_section_stabs): Add string offset
	parameter.
	* cofflink.c (coff_link_add_symbols): Deal with split stab
	sections.
	* elflink.h (elf_link_add_object_symbols): Deal with split stab
	sections.
	* stabs.c (_bfd_link_section_stabs): Add string offset parameter.
	* libbfd.h: Regenerated.
ld/ChangeLog:
	* ldwrite.c (unsplittable_name): New.
	(clone_section): Strip existing numeric suffix. Only truncate names
	for coff targets.
	(split_sections): Use unsplittable_name.
binutils/ChangeLog:
	* objdump.c (read_section_stabs): Just read one section, return
	pointer to it. Add size parameter.
	(print_section_stabs): Add string offset parameter. Adjust.
	(struct stab_section_names): Add string offset member.
	(find_stabs_sections): Correct check for split section suffix,
	adjust read_section_stabs and print_section_stabs calls.
	(dump_stabs_section): Clear string_offset, free string table.
