We have scheduled a few thousands of binNMUs on s390x due to the libc
ABI breakage. It occurs that most of the non binNMUs safe packages are
wrongly using this --link-doc option.

I am therefore increasing the severity of this bug. dh_installdocs
--link-doc should refuse to do links between arch:all and arch:any
packages.
