The [[https://github.com/llvm/llvm-project/issues/155606|github issue]] has details and various workarounds, and the root cause appears to be that while the LLVM compiler uses a specific algorithm to find include paths, it uses a different one to find libraries; so the system C++ standard library is being used instead of the LLVM-provided C++ standard library. Explicitly including the LLVM-provided library fixes this issue in the build.
