ucl: fix on Darwin/with `pkgsLLVM` 

Modern clang versions error with `-Wimplicit-function-declaration`
[by default]; this causes `ucl`'s `configure` scripts check for ANSI C
headers (`stddef.h`) to fail because its test assumes `exit` is
implicitly declared leading to build failures:
```console
checking for ANSI C header files... no
```

[by default]: https://reviews.llvm.org/D122983
