Silence these errors by disabling the tests if target uses SJLJ for
implementing exceptions. Use a new effective target check for this.
Ensured that test results with and without this patch for
x86_64-pc-linux-gnu are the same.
Ok for trunk?

OK, but please make sure to document the new dejagnu target test.
