Comment:

 The build of snowflake was failing with the error:
 {{{
 ./rendezvous.go:77:43: undefined: webrtc.SessionDescription
 ./rendezvous.go:78:3: undefined: webrtc.SessionDescription
 ./rendezvous.go:119:16: undefined: webrtc.Configuration
 }}}

 This is fixed by adding an `export CGO_ENABLED=1`. It seems that cgo is
 enabled by default, except when cross-compiling, which is the case when we
 build for linux-i686 on linux-x86_64, so the build of `go-webrtc` was
 missing the cgo parts.

 I am not sure if we should add this `export CGO_ENABLED=1` to `var/setup`
 in `projects/go/config`, so that it applies to all go projects, or add it
 only in `projects/go-webrtc/config` and `projects/snowflake/config`.
