The pthread_rwlock_rdlock() failures are caused by long standing bug in glibc see https://sourceware.org/bugzilla/show_bug.cgi?id=25619. For the rest of the failures you will have to look at the tests and figure out why yourself.

Also note that UNTESTED (and possibly some of the UNRESOLVED) are not failures, there is quite a lot of optional behavior in POSIX in the case of UNTESTED for shm_open() there simply is no artificial limit hence the call does not fail with ENAMETOLONG.
