ESP32使用文件系统时找不到头文件

dfs，libc和SFUD都已经打开了，但编译时产生如下错误：

```c
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: building associated VariantDir targets: build
CC build/kernel/components/dfs/dfs_v1/filesystems/devfs/devfs.o
In file included from /home/lzx/myrtt/rt-thread/components/dfs/dfs_v1/filesystems/devfs/devfs.c:14:

   21 | #include <sys/statfs.h>
      |          ^~~~~~~~~~~~~~
compilation terminated.
scons: *** [build/kernel/components/dfs/dfs_v1/filesystems/devfs/devfs.o] Error 
```
之后我将头文件改成绝对路径的方式可以编译这行代码，但产生新的错误：

```c
CC build/kernel/components/dfs/dfs_v1/filesystems/devfs/devfs.o
/home/lzx/myrtt/rt-thread/components/dfs/dfs_v1/filesystems/devfs/devfs.c: In function 'dfs_device_fs_getdents':

  363 |         d->d_namlen = RT_NAME_MAX;
      |            ^~~~~~~~

  364 |         d->d_reclen = (rt_uint16_t)sizeof(struct dirent);
      |          ^~
```
我怀疑是工具链的问题，文件系统的工具链并没有适配到scons构建系统，但不太确定，希望大佬指点
