Multi-arch builds with cgo deps?

[shell-skrimp]

This one is tricky I think. I have a cgo project that depends on some libraries and builds fine on both amd64 and arm64.

Sample yaml:

builds:
  - id: asdf
    main: ./cmd/asdf/main.go
    binary: asdf
    env:
    - CGO_ENABLED=1
    mod_timestamp: '{{ .CommitTimestamp }}'
    flags:
      - -trimpath #removes all file system paths from the compiled executable
    goos:
      - linux
    goarch:
      - amd64

If I add:

goarch
  - amd64
  - arm64

It'll fail with this error:

  ⨯ release failed after 9s                  error=failed to build for linux_arm64: exit status 1: # runtime/cgo

If I replace amd64 with arm64 and build on a dedicated arm64 system with the deps it builds fine.

How should I handle this with goreleaser? Just two separate files one for amd64 and one for arm64?
