gcc: revert libstc++-gdb.py installation changes
Commit dbb87d in the GCC 11 branch was intended to make the installation of this Python module more robust, but for unknown reasons the library_name in libstdc++.la in baremetal builds (for example, Zephyr) is unset, so the module is just installed as "-gdb.py". This may be a GCC bug, or a bug in our build. Until that is resolved, revert the commit to fix the packaging.
