Linux Driver Verification

After the build of ldv-tools I tried to clean the build tree. The command "make clean" failed with the following error log:

make -C rule-instrumentor clean

The Makefile for error-trace-visualizer doesn't contain the "clean" target, but it is called by the top level Makefile (make -C error-trace-visualizer clean).
