Remove completely.

I don't think we need to care about GPLv3 in the toolchain. I ported
gcc-4.4 in pkgsrc wip, so if that compiles base well (not sure if Sascha
did a whole world/kernel run with it), we could import gcc-4.4.

That's a pain, yes. But in the long run we won't have a choice, I think.
Porting is probably also only a one-shot thing.

Likewise I think we should move forward there.

Agree.

Will that be sufficient, will it work?

I think I started looking at gdb at some point. Will have to look again.
