If the user has the $LINGUAS environment variable set, only translations
for those languages should be installed to the system.

The gettext manual [1] says:

"Internationalized packages have usually many ll.po files. Unless
translations are disabled, all those available are installed together
with the package. However, the environment variable LINGUAS may be set,
prior to configuration, to limit the installed set. LINGUAS should then
contain a space separated list of two-letter codes, stating which
languages are allowed."
