Modify Coccinelle documentation to clarify usage of make command to
run coccicheck on a folder.
Changes in v2:
- Give example of folder instead of file
- Add note

err.log will now have the profiling information, while stdout will
provide some progress information as Coccinelle moves forward with
work.
+NOTE:
+
DEBUG_FILE support is only supported when using coccinelle >= 1.0.2.
+Currently, DEBUG_FILE support is only available to check folders, and
+not single files. This is because checking a single file requires spatch
+to be called twice leading to DEBUG_FILE being set both times to the same value,
+giving rise to an error.
