Subject: [PATCH] Add option to not check arch:all rdeps

This is useful when removing packages on some architectures that have
many arch:all rdeps.  We know these will break, but listing them
obscures which arch-dep packages will be broken.

Of course we will still break the possibly arch-dep packages of the
arch:all packages that will no longer be installable...
