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.
