I don't understand why you need to do this.  Why not just start up the
inferior gdb first and attach to it with another gdb while it's at the
prompt?  Once you're attached, you can set breakpoints wherever you
like.  After your breakpoints are set, do a ``continue'' and then
start entering your target connection commands in the inferior gdb.
Assuming you've placed a breakpoint somewhere along the execution path
that the inferior gdb will take when/after it connects, you'll be
stopped...
