Log:
  Pull in r357362 from upstream clang trunk (by David Chisnall):
  
    [objc-gnustep] Use .init_array not .ctors when requested.
  
    This doesn't make a difference most of the time but FreeBSD/ARM
    doesn't run anything in the .ctors array.
  
  This should help with updating the libobjc2 port for armv7.
