It's a 'feature' of the dependancy setup of the kernel.  bk -r get -q
will checkout all of the files everywhere, and the build _should_ work
(there's been times autogenerated files were in the kernel and thus
broke building from a bk repo).

I don't think they do now, but it wouldn't be too hard I'd think.  If of
course the files needed to build/run the tools get checked out :)

Don't -r edit, -r get.  You can go and selectively clean out some dirs,
but in short, no.
