Whoops! It's very good that you have such bad tests, otherwise we'd have 
performance troubles when it's not so easy to diagnose what's up.

To to gcc.jam and
1. Comment out the entire body of set-library-order (it's defined at the end).
2. Make 'order-libraries' return 'libraries' argument.

If that does not help, I'd like to take a look at the profile.

Thanks,
