I don't use meta-clang to check where does it install the llvm-config
scripts if it's different location than what we have in meta-oe or not,
but I assume khem was testing his mesa change with meta-clang's llvm.
Trevor, what layer were you getting llvm from? Khem's fix looks good from a "stop host contamination" point of view, so we either need to fix meta-something or mesa very soon as oe-core is very close to the final RC builds.
