--- Comment #5 from Sam James <sam at gentoo dot org> ---
What about this?

l.c:
```
[[gnu::visibility("protected")]] char **__environ;
```

a.c:
```
char **
__gnat_environ (void)
{
  extern char **environ;
  return environ;
}

int main() {
  __gnat_environ ();
}
```

```
$ gcc l.c -o l.o -mno-direct-extern-access -c
$ gcc a.c l.o -mdirect-extern-access -o a -ggdb3 -fno-PIE -no-pie -Wl,-z,text
/usr/lib/gcc/x86_64-pc-linux-gnu/16/../../../../x86_64-pc-linux-gnu/bin/ld:
/tmp/cc3DQUCr.o: warning: relocation against `__environ@@GLIBC_2.2.5' in
read-only section `.text'
/usr/lib/gcc/x86_64-pc-linux-gnu/16/../../../../x86_64-pc-linux-gnu/bin/ld:

```

(Same with PIE.)
