NPTL is disabled, probably because you have LD_ASSUME_KERNEL set in your environment.
This is bug #152838 iff /lib/tls was not installed. The more usual explanation for the behavior that LD_ASSUME_KERNEL was set to disable NPTL. In both cases, the behavior is because of non-functioning NPTL, rpm is built expecting posix mutexes using NPTL.
The other failure mode is if rpm was built without nptl-devel installed, or otherwise built with non- functional NPTL.
