golang.org/x/tools/go/packages tests are failing on Plan9:
https://build.golang.org/log/a8439e96692e223503e21df34d690fdc2bc75625
Specifically, when TestLoadImportsC loads syscall and net, the package "net [syscall.test]" is not among the loaded set. Disabling test for now. The task of this issue is a principled fix.
