Subject: [PATCH] m4: Increase warning limit for frame-larger-than.

Generated code in virt-builder causes the error below.  Since we
cannot control what is generated by bison, increase the limit.

index-parse.c: In function 'yyparse':
index-parse.c:1857:1: error: the frame size of 5152 bytes is larger than 5000 bytes [-Werror=frame-larger-than=]
