Don't leave a model whose build was failed.
Don't execute 'make install-modelname' when building model was failed.
autoburt for k1visbsp was not taken from 21:40 on Mar. 17th.
I applied autoburt at 20:40 on Mar. 17th.
I cannot restore the changes in last week.
Last build of k1visbsp at 21:30 on Mar. 17th was failed, but someone probably executed 'make install'.
Scripts (including autoburt) related with k1visbsp vanished at that time.
