GitHub Actions build fails when trying to use v8go

Failed build: https://github.com/plentico/plenti/runs/930279376#step:8:128

Looks like the issue is building binaries for windows or darwin (mac) with v8go:

See screenshot

Tracking progress on rogchap/v8go#7

Cross compiling is an issue for all modules that rely on CGO (like v8go): rogchap/v8go#35 (comment)

There is a docker container we could use (see https://medium.com/@robdefeo/cross-compile-with-cgo-and-goreleaser-6af884731222 and goreleaser/goreleaser#708 (comment)).

It looks like a 2nd docker image was added to Goreleaser: goreleaser/goreleaser#795 (comment)

I was able to get this working still using the Goreleaser GitHub Action. I needed to do the following things:

1. Break goreleaser into multiple builds: Conditional build flags or per-build hooks. goreleaser/goreleaser#459
2. Pass ldflags to fix errors like shown here: "failed to build for" error only in Github Action goreleaser/goreleaser-action#40 (comment)
3. Create an osxcross target like this that we can pull into the project as a GitHub Action step (more details here):

     -
        name: OSXCross for CGO Support
        run: |
          mkdir ../plenti-osxcross
          git clone https://github.com/plentico/plenti-osxcross.git ../plenti-osxcross/target

Additional cgo cross-compiling details:

• Cross-compile for Linux? rogchap/v8go#35
• Cannot compile with a cgo package goreleaser/goreleaser#795
