A feature has been proposed that, if implemented, will expose the number of 
times make has re-exec'ed.  It's similar to MAKE_LEVEL, but will count the 
number of times make started reparsing the makefiles.

If this feature existed, then I think something like the following should be 
doable:

ifneq ($(MAKE_EXEC_COUNT),0)
  ifeq ($(wildcard aoeu.mk),)
    $(error aoeu.mk: No such file or directory)
  endif
endif
