If you add gdb to xdev, it should just work... I did some work a while
back to make kgdb compile (but only kinda work)...
I've attached the patch... The reenabling of CTF was to help me get
the avila board back to being functional...
I don't remeber why I needed CDMAKE...
I do vaguely remeber that there might have been some ordering issues,
but I don't remeber right now...
Let me know how it works for you...
