From: Thomas Huth <thuth@xxxxxxxxxx> The tprot test currently does not have any output (unless one of the TEST_ASSERT statement fails), so it's hard to say for a user whether a certain new sub-test has been included in the binary or not. Let's make this a little bit more user-friendly and include some TAP output via the kselftests.h interface.
