The dummy implementation doesn't do anything (at runtime), but it does
compile (when CGO_ENABLED=0), which e.g. unbreaks some build bots.
The work_other.go file is new, faking what's in work.go.
The changes to the other (existing) files simply re-order the
GOOS-related build constraints to be in a consistent order (alphabetical
order), the same as the existing order in work.go.
