Subject: [PATCH] Fix external_path_test with newer Xcode versions.

I found this when running Bazel's test suite with Xcode 12.2:

```
external/remote/lib/lib.c:2:3: error: implicitly declaring library function 'printf' with type 'int (const char *, ...)' [-Werror,-Wimplicit-function-declaration]
  printf("Hello %s\n", s);
  ^
external/remote/lib/lib.c:2:3: note: include the header <stdio.h> or explicitly provide a declaration for 'printf'
```
