    config: allow to build tarball when yacc is missingmaster
    Autoconf does not handle this scenario as well as Automake does.
    If gram.c is already there, do not abort the configuration
    if yacc is missing as it is not needed.
    
    If both xkbparse.c and yacc are missing, abort configuration.
    Yacc is a required tool to build the package.
