I guess that at the current time we do support distros that are at max
10 years old, mostly because enterprise support cycles are about 10
years in lenght.

The issue here is that glibc needed -lrt passed to linker couple of
years ago and we wanted to avoid the need of linking everything with
-lrt, as calling the raw syscall was just easier fix.
