I see the following for Generic_ELF thingy:

  if (DriverArgs.hasFlag(options::OPT_fuse_init_array,
                         options::OPT_fno_use_init_array, UseInitArrayDefault))

NetBSD should be using that.  Could you verify with 'clang -v' whether
it's being passed to cc1?

I do and I can do that if we have enough info.  However, submitting
a patch is always a better option.
