Well, sure.  You've never told make which rule is creating a .tab.h
file, or even that you're ever creating one at all!  How can it know
when it should delete a file it knows nothing about?

You need to tell make that the invocation of bison builds both those
files, like this:

    %.tab.c %.tab.h: %.y
            $(BS) $(BSFLAGS) $^
