  #   <LOCALEDIR>/fr_FR.UTF-8/LC_MESSAGES/<domain>.mo
  #   <LOCALEDIR>/fr.UTF-8/LC_MESSAGES/<domain>.mo
  # Similarly, on Solaris 11 OpenIndiana and Solaris 11 OmniOS it looks only for
  #   <LOCALEDIR>/fr_FR.UTF-8/LC_MESSAGES/<domain>.mo
  # Reported at <https://www.illumos.org/issues/13423>.
  # On Solaris 11.4 this is fixed: it looks for
  #   <LOCALEDIR>/fr_FR.UTF-8/LC_MESSAGES/<domain>.mo
  #   <LOCALEDIR>/fr.UTF-8/LC_MESSAGES/<domain>.mo
  #   <LOCALEDIR>/fr_FR/LC_MESSAGES/<domain>.mo
  #   <LOCALEDIR>/fr/LC_MESSAGES/<domain>.mo
