<pre>
    C library file missing error when using toolchain.
Error is as follows：
```
In file included from hello.c:1:
/usr/include/stdio.h:27:10: fatal error: 'bits/libc-header-start.h' file not found
#include <bits/libc-header-start.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.
```
But once I referenced the GCC C library, compilation worked.
