Well, you mentioned _bfd_elf_rela_local_sym, but that's not what I
meant.   I'm talking about code in elf-m10300.c that does

	  isym = isymbuf + ELF32_R_SYM (irel->r_info);
	  if (isym->st_shndx == SHN_UNDEF)
	    sym_sec = bfd_und_section_ptr;
	  else if (isym->st_shndx == SHN_ABS)
	    sym_sec = bfd_abs_section_ptr;
	  else if (isym->st_shndx == SHN_COMMON)
	    sym_sec = bfd_com_section_ptr;
	  else
	    sym_sec = bfd_section_from_elf_index (abfd, isym->st_shndx);

	  symval = (isym->st_value
		    + sym_sec->output_section->vma
		    + sym_sec->output_offset);

then uses symval.
