 262    both USE_REL and USE_RELA ['twould be nice if such a critter existed],
 263    if only to serve as a learning tool.
 264
 265    The RELOCATE_SECTION function is called by the new ELF backend linker
 266    to handle the relocations for a section.
 267
 268    The relocs are always passed as Rela structures; if the section
 269    actually uses Rel structures, the r_addend field will always be
 270    zero.
 271
 272    This function is responsible for adjusting the section contents as
 273    necessary, and (if using Rela relocs and generating a relocatable
 274    output file) adjusting the reloc addend as necessary.
 275
 276    This function does not have to worry about setting the reloc
 277    address or the reloc symbol index.
 278
 279    LOCAL_SYMS is a pointer to the swapped in local symbols.
 280
 281    LOCAL_SECTIONS is an array giving the section in the input file
 282    corresponding to the st_shndx field of each local symbol.
 283
 284    The global hash table entry for the global symbols can be found
 285    via elf_sym_hashes (input_bfd).
 286
 287    When generating relocatable output, this function must handle
 288    STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
 289    going to be the section symbol corresponding to the output
 290    section, which means that the addend must be adjusted
 291    accordingly.  */
