When compel build objects it provides ".compel.init" and
".compel.exit" setions for plugins init/exit routines
and when we link PIE code in criu we simply zap them
out but code still reference to them inside std
text (even if we don't call them) so dont drop them.

Eventually compel will be loading plugins by self but
for now it's good for testing purpose to refernce
the plugin inside criu code.
