    games/openenroth: unbreak the port's build in pre-C++20 environments
    
    Pull Clang 13 when it's not available in the base (via USES+=llvm:13)
    and use Boost's ``unordered_map'' implementation while the system one
    is insufficient; avoid ``std::u8string'' for the same reason.
    
    Set LLD_UNSAFE to unbreak linking against OpenAL on i386 (ld: error:
    cannot preempt symbol: alGetError).
    
    While here, slightly wordsmith the installation message.
