Base checkout and make did not work can't find crate for `std`

[PastaPastaPasta]

I tried to check this out and build; however it didn't appear to work

> $ make                                                                                                                                                                                                                                                                                  [±main ✓]

I suspect this is run on an aarch64 computer, the hash that is pinned in this command is for a manifest list, so there are two different containers that may be used (x86_64-unknown-linux-musl and aarch64-unknown-linux-musl):

docker manifest inspect rust@sha256:8463cc29a3187a10fc8bf5200619aadf78091b997b0c3941345332a931c40a64

You can check the available toolchains like this:

docker run --rm rust@sha256:8463cc29a3187a10fc8bf5200619aadf78091b997b0c3941345332a931c40a64 ls -la /usr/local/rustup/toolchains/
