It seems libsmbclient has been GPLv3 for years. Also, it's certainly not LGPL (unlike some of its support libs like talloc). Thus, mpv built with Samba support is GPLv3. Disable it by default, so we don't have to go through the trouble to indicate the correct license in our output, and we don't trick people into distributing stuff under the wrong license.
