uts: Allow for address space randomisation.
Randomise the base addresses of shared objects, non-fixed mappings, the
stack and the heap. Introduce a service, svc:/system/process-security,
and a tool psecflags(1) to control and observe it

50 50 * -z nointerp suppress the addition of an interpreter
51 51 * section. This is used to generate the kernel,
52 52 * but makes no sense to be used by anyone else.

54 54 * -z norelaxreloc suppress the automatic addition of relaxed
55 55 * relocations to GNU linkonce/COMDAT sections.
