The source project of this merge request has been removed.

Build from the Dockerfile and copy the artifacts from the resulting image
Use cross-compilation at build stage when building for a foreign architecture
Use docker buildx build ... in CI to enable multiplatform builds. If buildx is not installed use: DOCKER_BUILDKIT=1 docker build ...
Gilab runner must expose tag 'multiplatform' which means it has native amd64 arch + emulated arm64 support: https://github.com/tonistiigi/binfmt/tree/deploy/v7.0.0-28#installing-emulators
```
  $ docker run --privileged --rm tonistiigi/binfmt --install arm64
```
Use lto = thin for release profile
