The patch will fix the "lib/clang/14.0.0/x86_64-unknown-linux-gnu/" issue on Debian/Ubuntu and their derivatives:
if Debian multiarch LLVM_DEFAULT_TARGET_TRIPLE=x86_64-linux-gnu is used, the `-unknown` should not be present.
I have noticed the issue on my Debian testing machine.

Whether this helps the revert of D107799 <https://reviews.llvm.org/D107799> (`-DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=on`): blind guess.
