What did you do?

I'm trying to compile a plugin.
The plugin code shares the model code from the main code, so I'm using the
import "myprog/model"
to get the common code.
If I leave this import out, the compilation works fine, but when I include it, I get the error shown in the title.
The same code compiles fine on darwin/arm64, linux/arm64, and linux/amd64.

go build -o plugin.so -buildmode=plugin plugin.go

@gopherbot please backport this to Go 1.22. This can cause build failure for plugins on darwin/amd64 without workaround. Thanks.

Backport issue(s) opened: #68122 (for 1.22).

Remember to create the cherry-pick CL(s) as soon as the patch is submitted to master, according to https://go.dev/wiki/MinorReleases.
