I would assume this is putting the code that *uses* libunrar in
KArchive, which is fine.  Obviously, putting libunrar itself in would
not be.

But, as Albert said, no distribution would ship a binary that linked to
libunrar, so that bit of code wouldn't get much use (distros would just
compile KArchive without unrar support).
