When linking KernelShark libraries we must take into account the
intrinsic dependency hierarchy of the trace-cmd libraries.
"libtraceevent" is the most basic one. "libtracefs" depends on
"libtraceevent" and "libtracecmd" depends on both "libtraceevent"
and "libtracefs". In order to guarantee a correct symbol resolution
during linking, those libraries must be listed in a reverse order
(the most basic comes last).
