Avoid crash when calling __localeconv_l with __C_locale
__C_locale is const. Thus, overwriting the lconv values in __localeconv_l
will try to write to a R/O region. Given the lconv values in __C_locale
are initialized, there's no reason to write them in __localeconv_l at all.
Just return &__C_locale.lconv.
