New version of the patch. I moved the logic to figure out GOOS/GOARCH to
the host side and added keywords to pass the information along to the
build side.

With a properly configured go package and perhaps some additional
qemu-binfmt targets packages like this should work:

(use-modules (guix packages)
             (gnu packages syncthing))
(package
  (inherit syncthing)
  (arguments
   `(,@(package-arguments syncthing)
     #:goos "plan9"
     #:goarch "amd64")))
