Simon Menke 4419d34488 go: allow building the cross-compilers
When the `--cross-compile` option is used the following runtimes will be build:

- darwin  (386, amd64; with CGO)
- linux   (386, amd64, arm)
- freebsd (386, amd64)
- openbsd (386, amd64)
- plan9   (386)
- windows (386, amd64)

Closes Homebrew/homebrew#12547.
