add #ifdef YYDEBUG in data/glr.c

[Florian Krohm]

The functions yypstack and yypdumpstack are for debugging purposes
only and should be guarded accordingly. Doing so also avoids compiler
warnings with -Wall.

        * data/glr.c: Guard the declarations of yypstack and yypdumpstack
        with #ifdef YYDEBUG.
