I'm going to do the hack fix first (has_version changing) and then keep the bug open for us to change to copying llvm's link test for robustness, as it'll cover manual /etc/clang config changes, etc.

Go for the hack for now, but keep the bug open as we want to switch to the proper link test from the LLVM ebuilds.

Build still fails in clean chroot with ::gentoo 28b0e6b360bc https // github com/gentoo/gentoo/commit/28b0e6b360bc fc974604fdfb -> 28b0e6b360bc *.log diff sans non-determistic build order build.log noise attached. Condition still evaluates to false, resulting in build failure, unless "use-libcxx" is locally hacked/moved to the outer block inside tc-is-clang for testing. I can't propose a .patch due to low experience with ebuilds.
I may well be missing something, but why does it evaluate to false with clang-common[default-libcxx]? WWhat is emerge -pvO clang-common for you?

I can't see how that test can possibly fail then. Please provide the logs in full, not just diffs, so I can try to spot the problem.

Reproduced & investigating.
Oh, duh. clang-common isn't slotted.
