name of makefile being processed

[Dan DeJohn]

Is there a way to refer to the name of the makefile from the makefile 
itself?

I need to rebuild a particular library if the makefile itself changes, 
in case additional object files are added to the list GEN_OBJ. Right 
now, I specify the path to the makefile as a prerequisite, which works 
OK, but will break if the makefile gets moved or renamed.

GEN_OBJ = a.o b.o c.o

$(GENLIB) : $(RDEV)/src/GNUmakefile $(GEN_OBJ)
           @$(RM) $(GENLIB)
           @$(AR) $(ARFLAGS) $(GENLIB) $(filter %.o,$^)

I'd really like to replace the $(RDEV)/src/GNUmakefile with something 
that evaluates to the name of the makefile being processed:

$(GENLIB) : $(MAKEFILE) $(GEN_OBJ)
           @$(RM) $(GENLIB)
           @$(AR) $(ARFLAGS) $(GENLIB) $(filter %.o,$^)
