If you want to mess with one of the stock Slackware packages without knowing what you are doing then at least check the Slackware-provided build script. It will show you that in Slackware, the default prefix is "/usr".
Why can you not just download and install the Slackware openssh package instead of compiling it with random parameters?
Edit: O sh*t, did not see that this thread was so old... the second today.
