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
requirements, then passing variable values over to the lower
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
  previous text).
