ccollect is a shell script and should work on all archs. Please test and mark.
Please, don't file such requests, ever. There's simply no reason to keyword stuff that noone uses on that arch. File bugs about arches that you actually care about and use yourself. Not to mention that the assumption that something is a script and so has to work everywhere is faulty, and dependencies of this ebuild are not keyworded on quite a few of the requested arches either.
