[DragonFlyBSD - Submit #2854] Support for place independent executables

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2854 has been updated by shamaz.

File pie_sysctl.patch added

If you wish to save the old behaviour, you can look at this new patch I am sending. It adds a new sysctl kern.elf64.pie_base_mmap (you may want to change both name and description, I cannot think out any better). If it is set to 1, vm_map_hint() is used, ET_DYN_LOAD_ADDR otherwise.

----------------------------------------
Hello. If you launch a PIE, the loader will map it in memory to a fixed
position (ET_DYN_LOAD_ADDR). This patch changes this behaviour and makes
the loader respect vm.randomize_map sysctl.
