  20    (_dl_init_paths) or thereabout and ensure that static binaries
  21    don't crash when expanding DSTs.
  22
  23    If the dynamic loader code linked into the static binary cannot
  24    handle expanding the DSTs e.g. null-deref on an incomplete link
  25    map, then it will crash before reaching main, so the test harness
  26    is unnecessary.  */
