I'm seeing something similar.
clang is using HOST_LINK_VERSION, obtained from ld64, as the default for
-mlinker-version. This causes Darwin.cpp to add the arguments you are
seeing, but not handled by lld. Perhaps -fuse-ld should be considered in
addition to -mlinker-version when adding these arguments.
As a workaround, you can try passing -mlinker-version. Looks like anything
< 133 will work, including 0.
