/*
 * This tests priv_gettext(). The priv_gettext() function always falls back to
 * the C locale if it can't find anything. To deal with that, we've defined a
 * dummy translation for the zz_AA.UTF-8 locale which has a translation for the
 * 'dtrace_kernel' privilege.
 *
 * Normally 'dtrace_kernel' has the following description:
 *
 *   Allows DTrace kernel-level tracing.
 *
 * In the zz_AA.UTF-8 locale it has the following description:
 *
 *   Ah Elbereth Gilthoniel
 *
 * We explicitly verify that things respect the global locale and per-thread
 * locale.
