I've added a different patch for these.  If somebody uses a compiler
without __dso_handle atexit() will not work as expected in the dlfcn
tests.  Therefore we'll simply bail out.

I would prefer to completely ban using anything before gcc 2.96 but I
think too many loosers will complain.  Let them get a broken glibc.
