[Bug nptl/5983] Stale threads from TD_TA_THR_ITER of the FORK child during PTRACE_SYSCALL

If you mean you rebuilt your own libthread_db to use with a previously installed
libpthread, then that is not expected to work.  libpthread and libthread_db come
as a pair built from shared source, and you need a new libpthread build if you
add something to structs.def.

Note that due to elfutils bugs your test case doesn't always work on x86_64 when
libpthread is not prelinked.  To include a regression test in glibc, we can't
rely on elfutils libraries anyway.  It might not be practical to make a test
case for this that fits into the libc suite.

I've committed an nptl_db fix to the trunk that I think should cover it.

See http://koji.fedoraproject.org/scratch/roland/task_531585/ for F-8 glibc with
the patch.  (sudo sh /etc/cron.daily/prelink after rpm upgrade.)
