    devel/llvm: enable clang when any runtime is built
    
    The runtimes are configured with the just-built clang, so on a clean 
system
    the default answers (all runtimes, no clang) fail with "could not find
    TARGET clang-resource-headers". Turn clang on whenever runtimes are chosen
    (directly, or through flang or lld). Also expand "all" only when it was
    chosen: the check looked at the list of choices, which always contains 
"all".
