Having clang++ doesn't mean it can still compile C++ apps. Similar to
having to build newlib and compiler-rt (LLVM's flavour of libgcc)
separately from the LLVM toolchain, for C++, we need to also build
LLVM's libcxx(rt) and libunwind. I haven't tested those yet for RISC-V
and I'm not sure if they build/work fine, hence I added that option.
