Implement #7495 as per Matt and Ingo's suggestions.

The various LC_ environment variables (as well as LANG) are set in
/etc/profile, based on the output of this new simple bin command locale.
LANG and LC_CTYPE are set based on the first preferred language, whereas the
formatting variables are all set based on the formatting conventions language.

The list of LC_ variables are from the locale command on Linux.

Based on my testing, at least the date command obeys these variables.
