 One more thing (but that can be a completely separate follow-up patch).

 Currently, in most cases, we clear the rpath completely. But patchelf also has
functionality to remove the RUNPATH entry in the dynamic section. Although this
doesn't really make the file smaller (the space for the original string is kept,
the old string is just overwritten with X's), removing the RUNPATH entry could
speed up dynamic loading slightly. It's also just weird to see these empty
RUNPATH strings when you do a readelf.

 The code to do that is already there, in the rpRemove section. It's pretty
simple to factor it out.

 Regards,
 Arnout
