OK, I found the problem. In Targets.cpp we have

  if (MajorVersion >= 9 && Opts.ObjC1 &&
      Triple.getArch() == llvm::Triple::x86_64)
    Opts.ObjCNonFragileABI = 1;

Keeping with the idea of doing feature checks in clang instead of
clang-cc, maybe the correct fix is to move this test to clang too?
