Redo the way we handle .l and .y files.
Use AC_PROG_LEX and AC_PROG_YACC to find {f}lex and yacc/bison/byacc.
Once we've found them, make sure {f}lex can handle -P, --header-file,
--nounput, and -o, and can parse our scanner.l, and make sure
yacc/bison/byacc can handle -p and -o. If that fails, fail, suggesting
that the user get versions that can (such as Flex and Bison/Berkeley
YACC). If that doesn't fail, use those options; don't use runlex.sh.
