Can a makefile identify itself?

[lists]

I want an included makefile to be able to identify itself (or atleast 
its directory).  Take the following example:

/prog/Makefile
/prog/apples/Makefile.mk


The /prog/Makefile uses "include apples/Makefile.mk" to call another 
makefile.  I need the apples/Makefile.mk to know where it is.  If I use 
$(shell pwd) I get the location of the root Makefile instead.  I'm using 
Make 3.79.1 (and am stuck with it) so I can't use the MAKEFILE_LIST 
variable.

Is there a nice way of doing this?
