Checked on x86_64-linux-gnu and i686-linux-gnu. * nptl/tst-rwlock6.c: Use libsupport. This also happens to fix a small bug where only tv.tv_usec was checked which could cause an erroneous pass if pthread_rwlock_timedrdlock incorrectly took more than a second. * nptl/tst-rwlock7.c, nptl/tst-rwlock9.c, nptl/tst-rwlock14.c: Use libsupport.
