2463. [port] linux: POSIX doesn't include the IPv6 Advanced Socket

                        API and glibc hides parts of the IPv6 Advanced Socket
                        API as a result.  This is stupid as it breaks how the
                        two halves (Basic and Advanced) of the IPv6 Socket API                          were designed to be used but we have to live with it.
                        Define _GNU_SOURCE to pull in the IPv6 Advanced Socket
                        API. [RT #18388]
