You're right.
This is a feature.
ln> For example, given a GNUmakefile like this:
ln> TARGET_NAMES:=phony-a phony-b phony-c
ln> d : $(TARGET_NAMES)
ln> phony-% :
ln> @echo Phony target is $@
ln> .PHONY : $(TARGET_NAMES) d
ln> ...making "d" results in nothing being echoed.
The GNU make manual sez (section "Phony Targets"):
Since it knows that phony targets do not name actual files that
could be remade from other files, `make' skips the implicit rule search
for phony targets (*note Implicit Rules::.). This is why declaring a
target phony is good for performance, even if you are not worried about
the actual file existing.
You are declaring an implicit rule "phony-%" but GNU make doesn't search
implicit rules for .PHONY targets.
You can make this work by using an explicit rule instead:
TARGET_NAMES:=phony-a phony-b phony-c
d : $(TARGET_NAMES)
$(TARGET_NAMES) :
@echo Phony target is $@
.PHONY : $(TARGET_NAMES) d
