No, gdb has a very simple model for thread debugging:
either all threads are running, or all are stopped.

* Theoretically, you might set a thread-specific breakpoint
and attach to it the command "set scheduler-locking on".
If your host / target supports scheduler locking, this 
would prevent any other thread from running, whereupon
you could simply "continue".

However, use at your own risk... it's a great way to
create a deadlock.  I haven't tried this, usual disclaimers
apply...
