-Subject: [PATCH] Do not check Go module-mode availability
-
-Since buildah vendorizes its dependencies we use buildGoPackage which
-does not uses Go module-mode.  The module-mode check will be true
-because nixpkgs uses Go 1.13 by default, and building go modules with
-buildGoPackage may lead to inconsistencies.
