Clang 16 does not allow `main` with an implicit `int`, which causes the configure script to misdetect clang as a non-working compiler. Patching `configure.in` and regenerating `configure` allows libelf to build. Due to the comment regarding bootstrap tools, this patching is only done on Darwin with clang.
