config: allow to build tarball when yacc is missing Autoconf does not handle this scenario as well as Automake does. If xkbparse.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. Acked-by: Daniel Stone <daniel@fooishbar.org> Reviewed-by: Kristian Høgsberg <krh@bitplanet.net> Signed-off-by: Gaetan Nadon <memsize@videotron.ca>
