Local fix

• In the Build Phases tab, remove the libraries libstdc++.sylib
  and the libc++.dynlib, and add libstdc++.6.dylib instead

Problem conclusion

• For hybrid applications, the project template was changed to use
  the library libstdc++.6.dylib instead of libstdc++.sylib and the
  libc++.dynlib.  For native applications, the documentation on
  creating a new native project has been updated accordingly.
  
  This fix is currently targeted for inclusion in fixpack 6.1.0.2.
