This is already supported in GNU make 4.0 and above; from the NEWS file:

* Setting the -r and -R options in MAKEFLAGS inside a makefile now works as
  expected, removing all built-in rules and variables, respectively.

Hi,

This was reported by a debian user. Please retain a CC to
 -email is unavailable-
so that the Debian BTS has a copy of your input.

What I do now is:

HAVE_NO_BUILTIN_VARIABLES_OPTION := $(shell echo $(MAKEFLAGS) | grep -e R)
ifndef HAVE_NO_BUILTIN_VARIABLES_OPTION
   $(error This makefile requires use of the -R/--no-builtin-variables option)
endif

which forces users of the makefile to do it.  But there should be a way to just do this from with the Makefile.  The implicit rules and default variable values represent the cruft of a bygone era and aren't worth all the trouble and confusion they cause.  And they were an ironic and bad idea to begin with,
since by definition and convention firm enough to merit them is just going to get put in somebodies IDE anyway: make is useful for the strange stuff and the custom work.
