The patch is not okay.

First, because I think it is not a problem if the build fails.  There 
are surely other targets that fail in the same way.

Second, because if anywhere the right place to put this is in config.gcc 
rather than by adding a new case $target statement. I wouldn't complain 
if it was placed there.
