Akim Demaille 5d9ccd5a87 yacc: declare yyerror/yylex only when POSIXLY_CORRECT ...

The recent changes to comply with POSIX are breaking Automake's test
suite.
Reported by Kiyoshi Kanazawa.
<https://lists.gnu.org/r/bug-bison/2021-09/msg00005.html>

To limit the impact of POSIX changes, bind them to $POSIXLY_CORRECT.
Suggested by Karl Berry.

changes.
