В gettext(3) написано следующее:

Translation lookup operates in the context of the current locale.
For the gettext and dgettext functions, the LC_MESSAGES locale facet
is used.  It is determined by a preceding call to the setlocale function.
setlocale(LC_ALL,"") initializes the LC_MESSAGES locale based on the first
nonempty value of the three environment variables LC_ALL, LC_MESSAGES,
LANG; see setlocale(3).  For the dcgettext function, the locale facet
is determined by the category argument, which should be one of the
LC_xxx constants defined in the <locale.h> header, excluding LC_ALL.
In both cases, the functions also use the LC_CTYPE locale facet in
order to convert the translated message from the translator's codeset
to the current locale's codeset, unless overridden by a prior call to
the bind_textdomain_codeset function.

The message catalog used by the functions is at the pathname
dirname/locale/category/domainname.mo.  Here dirname is the directory
specified through bindtextdomain.  Its default is system and configuration
dependent; typically it is prefix/share/locale, where prefix is the
installation prefix of the package.  locale is the name of the current
locale facet; the GNU implementation also tries generalizations, such as
the language name without the territory name.  category is LC_MESSAGES
for the gettext and dgettext functions, or the argument passed to the
dcgettext function.

If the LANGUAGE environment variable is set to a nonempty value, and
the locale is not the "C" locale, the value of LANGUAGE is assumed
to contain a colon separated list of locale names.  The functions will
attempt to look up a translation of msgid in each of the locales in turn.
This is a GNU extension.

Было бы разумно реализовать аналогичное поведение.
