This tells gcc to use DWARF based exception handling rather than
setjmp/longjmp exception handling.

There is no way to tell gcc to not support exception handling at all.
If you don't want to implement it, put something like this in your
OVERRIDE_OPTIONS function
  if (flag_exceptions)
    {
      sorry ("exceptions are not supported");
      flag_exceptions = false;
    }
