If used in the way you say not, however I think current default behaviour
contradicts this very much.
If this is what we want, make install should refuse to work on any
non-empty directory, and it "sure as hell" should not default to
install in /usr/local, because that can be quite a pain to get things
extracted out again without a uninstall target.
