I forgot about command line variations.
% cat cflags
.PHONY : a
a :
# ${CFLAGS}
make -f cflags dee-dee
dee-dee :
# ${CFLAGS}
% make -f cflags
# -O -pipe
make -f cflags dee-dee
# -O -pipe
% env CFLAGS="do-do" make -f cflags -E CFLAGS
# do-do
make -f cflags dee-dee
# do-do
%
And, amazing ! featuristic !
% make -f cflags -E CFLAGS CFLAGS=hehe
# hehe
make -f cflags dee-dee
# hehe
% echo $CFLAGS
CFLAGS: Undefined variable.
If the makefiles in nest don't have conflicting variable

strata makefiles seems not hard.
BTW,
o tested on 4.9-STABLE,
o /etc/make.conf is not mocked up one (as I wrote in
