DDD external target support?

[Martin Filtenborg]

Scenrio:
Evaluation board with Motorola mcore-processor, onboard monitor (picobug) 
capable of interfacing to GDB
Serial connection to (Intel x86-based) pc running Linux  & GDB
Complete sources to GDB, GCC, assembler, linker etc. for mcore target
Software needing debug.

What I want is to *include* DDD in this toolchain.

Snooping around in config.sub and similar places, I find that DDD can be 
compiled to run on various host-processors.
What I cannot deduce, is what it takes to make DDD interface to a given 
*target*...

Merely a version of GDB made for that target? Naaah, i don't believe so.
Then *what*?

Thanx in advance :)
