Hi, Andrew:

Here is several fixes for selftests.
For `make run_tests` the target command will cause make fail if it exit
with non zero codes. So I change the makefile as below:
 run_tests: all
-       /bin/sh ./run_vmtests
+       @/bin/sh ./run_vmtests || echo "vmtests: [FAIL]"

Also fixed the kcmp build error.
