As in, add a compiler-rt specific option to disable using libc++? Maybe something like `COMPILER_RT_DISABLE_LIBCXX` (or its positive version)? I have no opinions on that (I don't really work on compiler-rt), although I'm wondering if that flag should be in addition to the `LLVM_TOOL_LIBCXX_BUILD` check or just replace it.
