Use --enable-sjlj-exceptions when configuring gcc so that exception handling

Browse Source 
works for dynamicly linked executables.  Only tested so far on i386 with
  gcc 3.3.2.  But combined with the latest ldso updates, I can now get a
  dynamicly linked java helloworld app to run.
Add a config toggle for building gcj and libgcj.  The build runs fine
  through gcc-final but currently requires hand interventions to build
  gcc-target.  Again, only tested so far on i386.
