   The RELOCATE_SECTION function is called by the new ELF backend linker
1046
   to handle the relocations for a section.
1047
 
1048
   The relocs are always passed as Rela structures; if the section
1049
   actually uses Rel structures, the r_addend field will always be
1050
   zero.
1051
 
1052
   This function is responsible for adjusting the section contents as
1053
   necessary, and (if using Rela relocs and generating a relocatable
1054
   output file) adjusting the reloc addend as necessary.
1055

   This function does not have to worry about setting the reloc
1057
   address or the reloc symbol index.
1058
 
1059
   LOCAL_SYMS is a pointer to the swapped in local symbols.
1060
 
1061
   LOCAL_SECTIONS is an array giving the section in the input file
1062
   corresponding to the st_shndx field of each local symbol.
1063
 
1064
   The global hash table entry for the global symbols can be found
1065
   via elf_sym_hashes (input_bfd).
1066
 
1067
   When generating relocatable output, this function must handle
1068
   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
1069
   going to be the section symbol corresponding to the output
1070
   section, which means that the addend must be adjusted
1071
