This is because the locale code being a macro:

#if defined(__NO_TLS) || defined(__RUNETYPE_INTERNAL)
extern const _RuneLocale *__getCurrentRuneLocale(void);
#else
extern _Thread_local const _RuneLocale *_ThreadRuneLocale;
static __inline const _RuneLocale *__getCurrentRuneLocale(void)
{

        if (_ThreadRuneLocale)
                return _ThreadRuneLocale;
        if (_CurrentRuneLocale)
                return _CurrentRuneLocale;
        return &_DefaultRuneLocale;
}
#endif /* __NO_TLS || __RUNETYPE_INTERNAL */

What really puzzles me is that why the build picks up headers from the
running system.
