[PATCH] localeconv.3: Add description of the function is not thread-safe

[Peng Haitao <penght-BthXqXjhjHXQFUHtdCDX3A@public.gmane.org>]

Hi Michael,

The function "localeconv" returns a pointer to a structure which might be
overwritten by subsequent calls to `localeconv' or by calls to `setlocale',
so it is not thread-safe.
