[Bug corefiles/11957] cross-target core file registers are not supported

Looking at bfd/elf64-alpha.c, I don't see any core note 'grok'ing routines,
so it's not surprising that this would only work natively currently.

See below for a relevant snippet of bfd/elf.c that points the way.  For being
host-independent, the bfd backend needs to implement the
elf_backend_grok_prstatus callback, otherwise, we fallback to the host-dependent
elfcore_grok_prstatus.

static bfd_boolean
elfcore_grok_note (bfd *abfd, Elf_Internal_Note *note)
{
  const struct elf_backend_data *bed = get_elf_backend_data (abfd);

  switch (note->type)
    {
    default:
      return TRUE;

    case NT_PRSTATUS:
      if (bed->elf_backend_grok_prstatus)
	if ((*bed->elf_backend_grok_prstatus) (abfd, note))
	  return TRUE;
#if defined (HAVE_PRSTATUS_T)
      return elfcore_grok_prstatus (abfd, note);
#else
      return TRUE;
#endif
