Unable to cross-compile for i686-pc-windows-gnu (cross version out of date?)

[FrancisRussell]

Description

I've been attempting to cross compile a Rust project for i686-pc-windows-gnu on the ubuntu-latest platform, which appears to work fine until the linking stage. Related PR is here: FrancisRussell/zoog#17

Workflow code

Expected behavior

Compilation succeeds.

Additional context

From what I can tell, cross does support this target which is why I'm filing here first.

[FrancisRussell]

I've noted this in the log:

Warning: `cross` does not provide a Docker image for target i686-pc-windows-gnu, specify a custom image in `Cross.toml`. Falling back to `cargo` on the host.

However, cross does have an image for this target, and setting this image inside Cross.toml fixes the issue. Perhaps the version of cross being depended on is out of date? It is unclear to me how the dependency on cross is captured in this repository.
