I've only seen glibc doing that downcase-and-strip-hyphens thing to
the codeset part of a locale name when looking for locale definition
files.  Other systems like FreeBSD expect to be able to open
/usr/share/locale/$LC_COLLATE/LC_COLLATE directly without any kind of
munging.  On a Mac it's probably a little fuzzy because the filenames
are case insensitive...
