The traditional way is to use recursion.
If you're willing to require GNU make 3.80 or better, you can also use
order-only prerequisites (see the GNU make manual), although you still
have to declare them on every target.

Correct: the GNU make manual is very clear on this point.
gg> - setting MAKEFLAGS in the Makefile:
gg> MAKEFLAGS := $(MAKEFLAGS -o coinc)
ITYM:
MAKEFLAGS := $(MAKEFLAGS) -o coinc
or:
MAKEFLAGS += -o coinc
But that won't work as you discovered, plus -o isn't what you want; that
would declare that target as very old and wouldn't rebuild it.
