I haven't done a deep investigation, but at least gold has the following comment in its aarch64.cc:

  // Layout of .got and .got.plt sections.
  // .got[0] &_DYNAMIC                          <-_GLOBAL_OFFSET_TABLE_
  // ...
  // .gotplt[0] reserved for ld.so (&linkmap)   <--DT_PLTGOT
  // .gotplt[1] reserved for ld.so (resolver)
  // .gotplt[2] reserved
