The current implementation of CLinker::systemLookup can not find stdio functions like printf on Windows 10.

On Windows 10, we load ucrtbase.dll as a library for the system lookup. But, this dll doesn't contain many stdio functions, because they are implemented as inline functions in the standard library header files.

We can use a fallback library that exposes pointer to these functions. The fallback library would be compiled by a native compiler, which would generate the needed code for the inline functions in the fallback library. The pointer can then be looked up by the system lookup.
