PIE randomization
This patch is using mmap()'s randomization functionality in such a way that
it maps the main executable of (specially compiled/linked -pie/-fpie)
ET_DYN binaries onto a random address (in cases in which mmap() is allowed
to perform a randomization).
Origin of this patch is in exec-shield
(http://people.redhat.com/mingo/exec-shield/)
