Кросс-компиляция — это RUST

Я делаю кросс-компиляцию на своем ноутбуке для raspberry pi. Целевая тройка на моем ноутбукеx86_64-linux-gnuЦелевой триплет на моем raspberry piarm-linux-gnueabihfЯ использую УБУНТУ 20.04.

.cargo/confi.toml имеет

      [target.armv7-unknown-linux-musleabihf]
linker = "ld.lld"


[target.arm-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"

Однако я получаю эту ошибку
