Currently, coccicheck fails with only the message "coccicheck failed"
and the error code for the failure. To obtain the error logs,
one needs to specify a debug file using the DEBUG_FILE option.

Modify coccicheck to display error logs when it crashes unless
DEBUG_FILE is set, in which case, the error logs are stored in
the specified debug file.

Again, I have no idea.  But the runtime cost of these tests must be
microscopic as compared to the overall cost of make coccicheck.
