Comment:
The thing causing the build to fail on arm is generating shell completions. The `hut` package doesn't ship with completion scripts; you're meant to run `hut completion bash > hut.bash` to generate the script. There are two issues with this:
1. It seems like you need to set `build_helper=qemu` and run `hut` with `vtargetrun` in the post install stage rather than trying to run hut itself normally. Otherwise I don't think crosscompiles will work.
2. On arm (or maybe just crossbuilds in general) it seems like the binary for hut is not located in `$GOPATH/bin/hut` after compiling, but instead in `$GOPATH/bin/linux_arm64/hut`.

Number 1 seems to work fine with `vtargetrun`, but for number 2 I'm not sure the best way to handle this. I was thinking I could do something like `hutbin=$(find $GOPATH/bin -type f)` to get the `hut` binary path, but that throws a weird error message:
```

```

Another option would be a switch statement for the arm architectures, but both of these seem hacky and not ideal. Maybe there's a simple environment variable that points to the binary you just installed or something? Will look into this further when I get some more time. Just wanted to update with the current progress.
