$NetBSD: patch-src_llvm-project_llvm_cmake_modules_AddLLVM.cmake,v 1.15 2024/04/18 09:29:42 pin Exp $

On Darwin, use correct install-name for shared libraries.

Undo some of the RPATH magic so that cross-building
works inside pkgsrc again (indirectly eliminates $ORIGIN rpath
handling / editing, $ORIGIN handling is partially undone by cwrappers
in pkgsrc).
