If you are running a recent rkhunter version (probably anything from
1.3.2 or so) then it will use the prelink command itself to calculate
checksums. As such the false-positives from rkhunter resulting from
prelink running should be very small at worst. However, changes in
executable dependencies caused by prelinking can occasionally throw it a
wobbly :-)
