No. Just try an experiment:
.PHONY: all
all: real-target phony-target other-real-target
real-target: ; @echo $@
other-real-target: ; @echo $@
.PHONY: phony-target
phony-target: ; @echo $@
And you'll see the output is
real-target
phony-target
other-real-target
Try permuting the prerequisites of all and you see that Make traverses
them left to right. PHONY only affects whether the prerequisite will be
updated or not.
