you just need to add an `#ifndef LIBC_COPT_STDIO_USE_SYSTEM_FILE` around `#include "src/__support/File/file.h"`, so that it it's only included when we're not using the system's file. You'll need to add a similar check in the cmake so that `libc.src.__support.File.file` is only a listed dependency when in fullbuild.
