Hmm, I got it.  A variable, of course!

$ cat Makefile 
.PHONY: all f b foo bar
all: f b;

f:
	$(info	MAKE	foo)
	@$(MAKE) foo "RECURSIVE_MAKE_INFO=MAKE	foo:	"
b:
	$(info	MAKE	bar)
	@$(MAKE) bar "RECURSIVE_MAKE_INFO=MAKE	bar:	"

foo:
	$(info	$(RECURSIVE_MAKE_INFO)CC	foo)
	@sleep 1
	@echo errors from foo >&2
bar:
	$(info	$(RECURSIVE_MAKE_INFO)CC	bar)
	@echo errors from bar >&2


alx@debian:~/tmp$ make -j24 --no-print-directory 
MAKE	foo
MAKE	bar
MAKE	foo:	CC	foo
MAKE	bar:	CC	bar
errors from bar
errors from foo
alx@debian:~/tmp$ make -j24 --no-print-directory -Orecurse
MAKE	bar
MAKE	bar:	CC	bar
errors from bar
MAKE	foo
MAKE	foo:	CC	foo
errors from foo

Have a lovely day!
