1.7.3.4

The latest cross-prelink version tracks the prelink r190 SVN.

Fix two minor issues as well. If we remove the package, we would unprelink the filesystem after the rm was finished. This is incorrect.. we need to do this prerm.

Move the cron and cron configuration file to a new package split. This item is not valid for most embedded users.

1.7.3.4

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.
