external (cgo) linking - failure to build groupcache

[daniejstriata]

When building gdu 5.26.0 in COPR for the various rpm distros, the Fedora Rawhide builds fail with the error snip below. (All the other distros builds) I set the go build command like:
GO111MODULE=on CGO_ENABLED=0 go build \

Is groupcache requiring cgo on newer versions of go? Should I enable cgo for all builds or only Rawhide?

I think you need to remove -linkmode=external from gdu.spec. CGO is not used by Gdu or it's dependencies and should be disabled.
