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).

This is for external libc(e.g. mlib),
|
|
and NOT for newlib or picolibc which are inherent in the toolchains.
|
|
Usually, the external libc should be a software package and select
|
|
RT_USING_EXTERNAL_LIBC in software package's Kconfig
|
|
This option is not available for users to select.
