wrong usage of install_name_tool / error when repacking content of `.rustup`

When experimenting with repacking rust as package installed via rustup I stumbled over some error message in rattler-build which indicates that there might be a bug. This error happens when $PREFIX/.rustup is in the prefix, and I am on apple-silicon. Note that this bug might not be relevant as it probably can be prevented with binary_relocation: false or similar. Yet it might show a potential bug in rattler-build.

the build script is relatively simple and just does:

export RUSTUP_HOME=$PREFIX/.rustup
export CARGO_HOME=$PREFIX/.cargo

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y --default-toolchain=1.77.2
rustup default 1.77.2
rustup target add wasm32-unknown-emscripten

here is the relevant part of the output
