Description

$ go version go version go1.14beta1 linux/amd64
Does this issue reproduce with the latest release?
Yes.
What operating system and processor architecture are you using (go env)?
go env Output

What did you do?
From inside a module root directory, where pkg is a non main package.
go list -f 'Target: {{ .Target }}, Root: {{ .Root }}' ./pkg
What did you expect to see?
An empty Target, since with GO111MODULE=on the package archives are no more installed in $GOPATH.
What did you see instead?
Target: /home/manlio/src/go/pkg/linux_amd64/github.com/perillo/gocmd/pkglist.a, Root: /home/manlio/src/go
NOTE: if it is decided that Target will be left empty, I hope that Root will remain.
