I managed to reproduce :) An easiest way to reproduce simply run

	make criu -j 4

need to think how to fix it properly. Note the key moment here
is that by default, when we run build as "make -j 4" we hit
@all target, which has own prerequisites, in turn "make criu"
is a different explicit target, which prereq's are somehow
incomplete.
