[PATCH 01/27] lockdep tests: Display compiler warning and error messages

[Bart Van Assche]

If compilation of liblockdep fails, display an error message and exit
immediately. Display compiler warning and error messages that are
generated while building a test. Only run a test if compilation
succeeded.
