Follow-up Comment #1:

Alas, AC_PROG_LEX and AC_PROG_YACC do only check for the
possible alternatives (flex vs. lex, bison vs. byacc vs. yacc),
without any real option to bail out if none of them has been
found.

It's not really easy to extend that check without duplicating
much of the code of these macros.  Ideally, this should be
filed as a feature request to project autoconf so these
macros would optionally allow for code to be run if none of
the tools had been found.

Would you be willing in filing such a feature request?
