The test for success was added to avoid build problems later on when
people didn't have bison or yacc installed. The warnings were pretty
obscure. In fact I think the missing script basically creates an empty
rp2gen_parser.c, which then results in a lot of obscure warnings during
the link phase that don't really indicate that the 'generated' parser
code is really an empty file.

So if AC_PROG_YACC does the right thing already, but only fails to set
the ac_cv_prog_YACC variable when /usr/bin/yacc is installed, then I'm
just testing the wrong variable.
