Uh, not quite, there was a difference.

Seems clear to me, #1 means installed in /usr.  #3 means installed
in not /usr and not /usr/local.  The whole point is where things get
installed.  FHS says we do not ever install in /usr/ (only distros may),
we need to respect that.  By using DESTDIR you prevent that, So very
different cases.
