This is possibly due to prelink?

See 'man prelink'

"prelink  is  a  program  which  modifies  ELF shared libraries
and ELF dynamically linked binaries, so that the time which dynamic
linker needs for their  relocation at  startup significantly decreases
and also due to fewer relocations the run-time memory consumption
decreases too (especially number of  unshareable  pages).  Such
prelinking  information  is  only  used  if  all  its dependant
libraries have not changed since prelinking, otherwise programs are
relocated normally."
