  Log:
  SVN rev 211729 on 2010-08-24 00:23:40Z by rpaulo
  
  Mark the following static variables as __used__ instead of __unused__:
  o force_to_data
  o __CTOR_LIST__
  o __do_global_dtors_aux_fini_array_entry
  o __frame_dummy_init_array_entry
  
  This is necessary because Clang is smart enough to optimize out these
  variables was they were marked as __unused__ (and they are also static).
  The end result was programs segfaulting because these symbols weren't
  present.
  
  This follows the upstream revision 159228 and the author of that
  revision (Jan Hubicka <jh at suse.de>) allowed us to backport this to our
  GPLv2 GCC.
