* configure: use move-if-change from gcc to create config.status.
Some makefiles depend on config.status to tell if a directory
has been reconfigured for a different host. This change
prevents those directories from remaking everything in the case
where the reconfig was only intended to rebuild a Makefile.
* configure: test for config.sub with "config.sub sun4" rather
than "config.sub ${host_alias}". Otherwise we can't tell a bad
host alias from a missing config.sub.
