Fix segfault in yacc

Browse source 
The patch to heirloom-devtool's yacc used sprintf instead of snprintf.
This incompatibility causes a segfault when those code paths are hit.
Fixing this allows yacc to compile more grammars, and may allow some
packages to drop dependency on bison in favor of yacc.
