OpenBSD's setlocale() accepts fr_FR.UTF-8 and ja_JP.UTF-8, so the
locale.fr_FR.UTF-8 and locale.ja_JP.UTF-8 lit features are enabled,
but only LC_CTYPE is implemented. LC_TIME always behaves as "C", so
the tests expecting French and Japanese day/month names, AM/PM
strings, eras and alternate numerals fail.
