I'm confused, that patch has a test that shows loading a library through `System.loadLibrary` working, and I remember seeing those patches in the JDK, and thought `loadLibrary` support was working on AIX as well now. Why doesn't that work for clang? Is it possible to change the way you're building clang to not use an archive member?
