cross compile failed with go 1.6 for windows x64 on OSX10.11

[monotone]

Hi, I could cross compile success for other GO library. But when I cross compile for this library, it failed.

 ✘  ~/code/go/src/github.com/pebbe/zmq4   master  GOOS=windows GOARCH=amd64 CGO_ENABLED=1 go build
# runtime/cgo
clang: error: unknown argument: '-mthreads'

I have no experience with crosscompiling with C source. Perhaps someone on golang-nuts can help you:
