	after AC_CANONICAL_HOST and default setting of $machine et al. Don't set $subdirs from $add_ons. Instead, source add-on/configure fragments early on. (base_machine): If it's already set, don't set it based on $machine. (libc_config_ok): New variable, set to no. If an add-on fragment sets it to yes, skip the tuple sanity check as if --enable-hacker-mode. (sysnames): Try appending add-on names after machine as well. * configure: Regenerated. * config.make.in (add-ons): Set from @add_ons@ instead of @subdirs@. * Makeconfig ($(common-objpfx)config.status): Also depend on configure files in $(add_ons) dirs. * sysdeps/unix/sysv/linux/bits/in.h (struct ip_mreq): Remove definition, now in netinet/in.h proper. long. Rewrite example code so that it takes into account l64a output
