The directive is:

        .comm   gnu_lto_v1,1,1

This apparently comes from here:

  /* Emit LTO marker if LTO info has been previously emitted.  This is
     used by collect2 to determine whether an object file contains IL.
     We used to emit an undefined reference here, but this produces
     link errors if an object file with IL is stored into a shared
     library without invoking lto1.  */
  if (flag_generate_lto)
    fprintf (asm_out_file,"\t.comm\tgnu_lto_v1,1,1\n");
