[linuxulator] Linux X11 programs: xauth snag

[soralx at cydem.org]

 For anyone who is getting "X11 connection rejected because of wrong
 authentication" error when trying to start GUI programs via linuxulator,
 here is a solution: swap the lines
    ::1         localhost
    127.0.0.1   localhost
 in /etc/hosts to move the IPV6 localhost address below the IPV4 one.
 This applies to FreeBSD base since r64664 by itojun. I am not sure
 why the order was changed.

 The real issue is likely to be elsewhere (e.g., in some linux-c7-*
 library), and this is just a symptom, but I can't be bothered to
 dig deeper. Perhaps a pkg-message about this can be added for
 ports/x11/linux-c7-xorg-libs?

Example:
  # /compat/linux/bin/bash
  bash-4.2# xterm
    X11 connection rejected because of wrong authentication.
    [...]
    xterm: Xt error: Can't open display: %s
  bash-4.2# baudline 
    X11 connection rejected because of wrong authentication.
    ERROR, XOpenDisplay((null)) failed
  <edit /etc/hosts as described>
  bash-4.2# xterm
  <xterm fires up>
