How to cross compile Go with CGO programs for a different OS/Arch

It is possible to compile Go programs for a different OS, even though go build says otherwise.

You'll need:

• a valid toolchain for the platform/os you're targetting
• Go Tip (works on 1.1 and 1.2rc1 but you might as well be on tip)
• golang-crosscompile helper script https://github.com/davecheney/golang-crosscompile
• the patch provided
