OS X's terminal application sets the LANG environment variable, so when
Emacs is run from there it picks up LANG. When run from the GUI (dock,
or spotlight or whatever) OS X does *not* set the LANG variable, so
Emacs doesn't pick it up.

It looks like the right way to get the locale from OS X is something
like:

const char * locale = [[[NSLocale currentLocale] localeIdentifier] UTF8String];

HOWEVER, it appears the actual bug reported:

is fixed in emacs 25. Or, at least, I can't reproduce it.

Not having LANG set does break ispell checking with hunspell on OSX, for
me at least, so it would still be nice to have the locale stuff fixed.
Presumably there are other reasons for wanting Emacs to have the correct
locale, too.

Should that be a new bug report?
