Pretty much cross-compile doesn't work because of this: > profiles/seccomp/seccomp.go:13:2: build constraints exclude all Go files in /go/src/github.com/docker/docker/vendor/github.com/seccomp/libseccomp-golang This changes adds a new Dockerfile target for cross compilation with the neccesary arch specific libseccomp packages and CC toolchains.
