ncurses: fix linking with `lld` 17+
Another fix like #309884 for fallout from `lld` 17's `--no-undefined-version` default + hard error. For context: - https://github.com/llvm/llvm-project/commit/241dbd310599e3c1a0f1b0c9ced14c8b8760539e - https://reviews.llvm.org/D135402 - https://github.com/llvm/llvm-project/issues/61208 Error
