During the initial attach normally all the threads get attached and they get
stopped by the attachment. Later you can have stopped only one specific
thread by using non-stop mode:
$ info '(gdb)Non-Stop Mode'
To not to stop the other threads at all one needs to disallow finding
gdbserver the file libthread_db.so.1, besides reconfiguring GDB as a safe bet
you can rename/hide it on the PPC board. `info threads' shows only the
single/initial thread.
(Assuming GNU/Linux environment on the PPC borad; you did not say.)
