Well... yeah. But... ugh! :-|
You're invoking that shell EVERY TIME you evaluate CFLAGS; and I mean
_in addition to_ the shell that's actually doing the echo.
If you're going to do this you might as well use make's builtin $(if
...) function instead of calling out to the shell:
CFLAGS += $(if $(filter $@,$(P)),-g)
Note that (a) you don't need the foreach even the way you wrote it
originally because filter tests _each_ of its arguments against each of
the possibilities; there can be more than one, and (b) if you swap them
(since $@ is only one item) you'll get better performance.
If it were me, I'd still probably use target-specific variables rather
than something like the above. Seems cleaner to me.
But, either of these is better than using $(shell ...), IMO.
Cheers!
