If the user previously had the prelinker installed onto the target, and had the
cron system installed to run the daily scripts, and never bothered to configure
prelink before..  whenever the script ran it would undo any prelinking that had
occurred.

After the change, it's now optional to install the cron scripts.  If they are
installed, they default to -on- which means that if cron runs the script it will
attempt to update the prelinking on the system.

This does not affect the build-time prelinking in any way.  For many systems
there is no reason to have the prelinker on the target, it's only needed for
field upgrades.

So, I consider this an enhancement (splitting the script out to make it
optional), and a bug-fix -- enabling re-prelink functionality if the script is
installed -- vs the previous "un-prelink" being the default.
