-        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). However, no matter the cover level
-        it is, the rt-thread libc leveling layer will not be involved
-        at all if select this option.
