Bug Description

As seen at https://launchpad.net/~mwhudson/+archive/ubuntu/devirt/+build/9828197, this combination fails to build:

collect2: error: ld returned 1 exit status

I've reported this upstream (https://github.com/golang/go/issues/15885) and hacked up a fix which I'll attach in a moment.
