control: severity -1 important This is a multi-arch problem and therefore not grave. mono-runtime-common is installable on a pure i386 system.
mono-gac and mono-4.0-gac should be converted to Architecture:any to relay the architecture constraint of the dependency to libc6. (mono-gac depends on mono-4.0-gac depends on libc6) Also the binutils dependency needs to be changed to binutils-for-host. All calls to binutils need to be prefixed with "$(DEB_HOST_GNU_TYPE)-".
