Individual tests that fail are usually fine as long as the overall configure/cmake script completes.  The reason for these configure-time tests is because Bro has to work on various platforms and with differing versions of some libraries, so it has to check what is actually available to use and adjust accordingly.  If the configure step completes, take that to mean “no problems detected so far”.
