Log:
  csu: Fix dynamiclib/init_test:jcr_test on !HAVE_CTORS archs
  
  .jcr still needs a 0-entry added in crtend, even on !HAVE_CTORS archs, as
  we're still getting .jcr sections added -- presumably due to the reference
  in crtbegin. Without this terminal, the .jcr section (without data) overlaps
  with the next section and register_classes in crtbegin will be examining the
  wrong item.
