Motivation for this change

Go 1.13 slightly changed the behavior GO111MODULE=auto [1], which might
accidentally cause the go command to build the module, for instance in
the checkPhase.

[GO111MODULE=auto] activates the module-aware mode of the go command
whenever the current working directory contains, or is below a
directory containing, a go.mod file — even if the current directory
is within GOPATH/src.

[1] https://golang.org/doc/go1.13#proxy-vars

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

that's a lot of rebuilds, staging would be more appropriate

Does this change break builds with older Go versions?

It shouldn't, prior to Go 1.13, GO111MODULE=auto does not enable module-mode inside GOPATH https://github.com/golang/go/wiki/Modules#when-do-i-get-old-behavior-vs-new-module-based-behavior
