803: add `CROSS_CUSTOM_TOOLCHAIN` to disable automatic target component downloading r=Alexhuszagh a=Emilgardis This adds an environment variable `CROSS_CUSTOM_TOOLCHAIN` to disable some rustup commands. The way to use this with `cargo-bisect-rustc` is `cargo bisect-rustc --script=./bisect.sh --target powerpc64le-unknown-linux-gnu` and the script is ```sh #!/usr/bin/env bash export CROSS_CUSTOM_TOOLCHAIN=1 exec cross run --target powerpc64le-unknown-linux-gnu ``` I've filed rust-lang/cargo-bisect-rustc#159 to avoid the pitfall that was discovered when not specifying `--target` resolves #699 Co-authored-by: Emil Gardström <[email protected]>
