[错误] [Smart][musl] 内核态调用 musl `fopen` 因 syscall 号位错配而失败，按下 finish 键无反应

The RT_USING_NEWLIBC branch of stdio.c uses newlib, which has a full set of weak hooks for system calls (such as _open_r, _read_r, and _write_r). This means that newlib does not have the same problem as musl, which has no kernel-level hooks.
