This happens sometimes, it's unclear why. If you do cargo clean it should fix itself.

See #724 which we're using to track this error

[Emilgardis]

Regarding x86_64-unknown-linux-gnux32, we do not have that target, cross should've made a warning saying that it's falling back to the host system

Ok, thanks~

FYI: we've just made this public, so if you'd like to support this target, it's a perfect issue or PR to this repository:
https://github.com/cross-rs/cross-toolchains

We don't plan (likely) on adding it to our main repository, however, it sounds like a perfect inclusion for an additional image as it's a tier 2 target.
