Does anyone have any advice here?

The issue is that the Go build tools typically want the source code to
be unpacked in a directory structure based on the URL of the Git repo.
We can set it "by hand" in the package definition, which is what the
current go-build-system patches do, but it would be great to have a
default that worked most of the time.
