This option is for RT-Thread Nano version. If select this option, it will not compile components/libc folder and only use tool chain internal libc. Normally, the tool chain internal is only cover ISO standard (e.g. armcc), but some tool chains' internal libc will cover more than ISO standard (e.g. newlib).
