    Convert libllvm, libclang and liblldb into private shared libraries
    
    This allows clang, lld, lldb, and other llvm tools to be linked against
    these shared libraries, which makes them smaller and avoids duplication.
    
    Since these are not quite the same as the shared libraries shipped by
    the upstream llvm build system, and we do not want to expose the ABI to
    external programs such as ports, make them private libraries.
    
    Note that during the cross-tools stage they are still built as static
    libraries, so the cross compiler and linker are static binaries, as they
    have always been.
    
    This also requires a depend-cleanup.sh kludge which will be added in a
    follow-up commit, to ensure binaries are rebuilt against the shared
    libraries in case of incremental builds.
