No - you'd need the whole network stack included with the application.
Once you have GDB stubs in your application, they take over the GDB debug
operation.  Since our stubs only know how to handle serial, unless they
are extended via RedBoot, you'd pretty much be stuck here.

It would be possible to build a stand-alone application which supports
GDB debugging via the network.  However, you'd pretty much end up with
everything from RedBoot (you'd need the RedBoot network stack, not the
generic TCP/IP stack from eCos) tucked into your application.

... probably not what you really wanted.
