OK, I added a `missing' script, similar to the one that is distributed
with automake, except that it never tries to create any output files
(it will exit with a warning and failure status).

Now if bison is missing, Octave's configure script will set the YACC
to '$(top_srcdir)/missing bison' so when you try to use $YACC, you
should see a warning message and make should quit.
