Yup.  Have him specify the flags on the commandline:

$ make -f make_0 CFLAGS="-g"

By the way, it's standard practice in some circles to
have the Makefile's CFLAGS include $EXTRA_CFLAGS or
something like that, where EXTRA_CFLAGS is empty.
That way the user can *add* flags easily by overriding
EXTRA_CFLAGS.
