Cross install is not supported. As you have seen, certain tools are bootstrapped on the build host and used during the install process. You might be able to get away with nuking /usr/obj/usr/src/arm64.aarch64/tmp/legacy (or maybe tmp) and then running `make toolchain` to build native versions of those tools. -- Brooks
