I agree with @llvm-beanz but I'd propose going even further and removing this option altogether. Rather than having separate `CLANG_ENABLE_<TOOL>` options for each tool which doesn't scale very well, we should encourage developers to use `LLVM_DISTRIBUTION_COMPONENTS` to control which tools to build.
