remember that -e affects more than just CFLAGS ... ive seen many makefiles use
simple internal variables that when you run `make -e` with, things break
everywhere (for example, python uses the makefile variable 'LIBC' but if you
have LIBC set in your env, python blows up with a really weird error message)

yes :)
try this:
CFLAGS ?= -g
