You can use 'make -e', or you call test cases directly, without 'make',
or you pass YACC as make command-line argument.  How is this different
from other variables set in makefiles?

I'm actually quite ambivalent on this one, but I guess my point is that
you might have to reconsider anyway at the point where YACC is used
anywhere in the makefiles (which could arguably be the case for creating
some tests or so).  If you need a comparison, why should it be treated
differently from PERL in the Automake package?
