  libstdc++6-*-dbg doesn't contain gdb Python hook

Bug description:
  libstdc++6-4.6-dbg and other -dbg packages for libstdc++ include the
  new Python pretty printers for debugging STL classes under gdb.
  However, they don't get loaded automatically, and require manually
  modifying gdb's python's sys.path.

  The gcc-snapshot package contains /usr/lib/gcc-
  snapshot/lib/libstdc++.so.6.0.17-gdb.py, which causes the pretty
  printers to get autoloaded whenever gdb attaches to a process that
  links /usr/lib/gcc-snapshot/lib/libstdc++.so.6.0.17.

  libstdc++6-4.6-dbg appears to lack this file (which can go either next
  to the original library or next to the debug symbols under
  /usr/lib/debug), as do the -dbg packages for libstdc++ in other gcc
  versions available.

  In the gcc source packages, the gdb autoload file is generated in
  src/libstdc++-v3/python. The Makefile installs it next to the library,
  but I can't follow the gcc packaging well enough to suggest a patch
  for non-snapshot builds.

  The pretty printers make a huge difference in debugging C++ code that
  uses STL containers. It would be very helpful if these were loaded by
  default for non-snapshot builds of gcc.

  For other examples of auto-loaded debugging code, see python2.7-dbg
  (/usr/lib/debug/usr/lib/libpython2.7.so.1.0-gdb.py) and libglib2.0-dev
  (/usr/share/gdb/gdb/auto-load/libglib-2.0.so.0.3000.0-gdb.py and
  libgobject-2.0.so.0.3000.0-gdb.py)
