I recently found some "could not contact jobserver" in the logs from make and googling it suggested that this is a consequence of using $(MAKE) rather than $$(MAKE) inside of macros (causing premature or too much expansion?). I have not investigated yet and don't know what counts as "macro" here. Or whether this is all nonsense. Either way, it should affect Guile-2 just as much as Guile-1.8, shouldn't it? https://codereview.appspot.com/569390043/
