--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For a cross from x86_64-linux-gnu to aarch64-linux-gnu produces:
  if (ptr->x_aarch64_branch_protection_string)
    fprintf (file, "%*s%s (%s)\n",
             indent, "",
             "aarch64_branch_protection_string",
             ptr->x_aarch64_branch_protection_string);
