Because the s390 version won't set up vdso if it is 0. It
is safe to assume that if we are calling special_mapping_restore()
then there is a vdso in the checkpoint image, and if that is
the case then the checkpointed program was dynamically linked.
Other architectures ignore uses_interp so this shouldn't
matter to them.
