a strong monotonicity is a property of system_time(). Performance should be
a bit impacted (around 10%).
removed omit-frame-pointer hints as the compiler generates the same without.

system_time: Add temporary hack for GCC 8 to get ia32intrin.
ia32intrin isn't supposed to be included, only x86intrin is,
but GCC 8 changed some of the __builtin definitions in a

So, this is a temporary hack until we are using GCC 8 syslibs
packages.
