When building with `--with-lto`, an explicit check for `llvm-ar` is performed as part of the configure step. However, Apple does not ship `llvm-ar` as part of Xcode, so when building with Apple Clang this check fails and prevents using `--with-lto`.

However, using the builtin `ar` seems to work just fine, and it can be selected by passing `LLVM_AR=/path/to/ar` to `configure`. It would be nice to see the `configure` script updated to know that system `ar` is sufficient when using Apple Clang on macOS.

Please see https://github.com/Homebrew/homebrew-core/pull/70177 for additional background.
