Good catch!

Uh, working around the problem this way adds overhead to a
lot of places where it wasn't before.  How about just
initializing the shortcut completely?

Worse comes to worse, call localeconv() in a .init by abusing
the G++ linker set that gets run to construct virtual base
clases and template classes the first time.
