There are

template<int size, bool big_endian>
class Output_data_got : public Output_section_data_build
{
 public:
  typedef typename elfcpp::Elf_types<size>::Elf_Addr Valtype;
  typedef Output_data_reloc<elfcpp::SHT_REL, true, size, big_endian> Rel_dyn;
  typedef Output_data_reloc<elfcpp::SHT_RELA, true, size, big_endian> Rela_dyn;
....
  bool
  add_local(Sized_relobj_file<size, big_endian>* object, unsigned int sym_index,
            unsigned int got_type);

  // Like add_local, but use the PLT offset of the local symbol if it
  // has one.
  bool
  add_local_plt(Sized_relobj_file<size, big_endian>* object,
                unsigned int sym_index,
                unsigned int got_type);

  // Add an entry for a local symbol to the GOT, and add a dynamic
  // relocation of type R_TYPE for the GOT entry.
  void
  add_local_with_rel(Sized_relobj_file<size, big_endian>* object,
                     unsigned int sym_index, unsigned int got_type,
                     Rel_dyn* rel_dyn, unsigned int r_type);

  void
  add_local_with_rela(Sized_relobj_file<size, big_endian>* object,
                      unsigned int sym_index, unsigned int got_type,
                      Rela_dyn* rela_dyn, unsigned int r_type);

The "size" parameter is the ELF class size.  32bit ELF targets
have to use 32.
