make question (target dependent variable)

[James]

The goal is to set CFLAGS differently for different targets.
test-1.mk works (see below), but I have hundreds of targets, so to
shorten the makefile,
I am trying something like test-2.mk, which fails. Any idea?
Basically, can I defer the expansion of CFLAGS (with $@) until the
evaluation of the rules for the target? I tried functions like "define"
or "eval" but failed.
--------------------------------------
$ cat test-1.mk
P = pp qq
T = pp rr
CFLAGS = -c

.PHONY: $(T)
all: $(T)
pp: CFLAGS += -g
pp:
        @echo $@ $(CFLAGS)
rr:
        @echo $@ $(CFLAGS)
--------------------------------------
$ make -f test-1.mk
pp -c -g
rr -c
--------------------------------------
$ cat test-2.mk
P = pp qq
T = pp rr
CFLAGS = -c
ifneq ($(strip $(foreach f,$(P),$(findstring $(f),$@))),)
CFLAGS += -g
endif

.PHONY: $(T)
all: $(T)
$(T):
        @echo $@ $(CFLAGS)
--------------------------------------
$ make -f test-2.mk
pp -c
rr -c
