Oh, and beware of master and dunfell with llvm-config, if your target is multilib.
You may need the patch referenced in

Did you check that llvm-native is listed in the sysroot-providers folder, and that tmp/sysroots-components/x86_64/llvm-native/ contains the expected files ?

That's odd, I can build:
using just oe-core from about a week ago. I don't have clang installed
on that builder. Check the git history between your version and master.
I don't see anything below from a quick look.

Can you try building master?
