    profiles/features/clang: add LLVM_USE_LIBCXX, CXXSTDLIB
    
    Needed to build some Rust crates like sys-apps/uutils.
    
    I'd heard some users mention needing to set this but hadn't
    poked particularly far (was in the context of trying to do
    Firefox + libc++ on non-LLVM profiles IIRC).
