Yes, and the easy way to avoid that is to have Clang use the macOS
provided libc++.so, by commenting out the .include lines:

    .include "../../lang/compiler-rt/buildlink3.mk"
    .include "../../lang/libcxx/buildlink3.mk"
    .include "../../lang/libcxxabi/buildlink3.mk"
    .include "../../lang/libunwind/buildlink3.mk"

and just keep

    CMAKE_ARGS+=    -DCLANG_DEFAULT_CXX_STDLIB:STRING="libc++"
