Adding Mark to this subthread. Concretely, could you please disable --with-llvm on any of those machines running LLVM < 7? And report what version any remaining animals are running? (It'd be nice if the build farm logged "$LLVM_CONFIG --version" somewhere.) One of them seems to have clang 5 which is a clue -- if the LLVM is also 5 it's just not going to work, as LLVM is one of those forwards-only projects that doesn't back-patch fixes like that.
