Bug#1107126: is cross-gcc-dev still useful or can it be removed?

Hi. I'm pretty sure you (Helmut) were the only user of cross-gcc-dev. As
you say, I haven't updated it for a while, and it hasn't been useful to
you either. So I don't see a lot of reason to keep it in the archive,
and removing it would be good.

Thanks for all your work!
