[Fedora-packaging] Usage of {_libdir} or {_lib} in noarch packages

I've run a x86_64 mass rebuild of all our Fedora packages and found several noarch packages which erronously use {_libdir} or {_lib} in their spec files. rpmdiff shows this output: ./firstaidkit-0.2.2-5.fc11.noarch.rpm removed /usr/lib/firstaidkit removed /usr/lib/firstaidkit/plugins added /usr/lib64/firstaidkit added /usr/lib64/firstaidkit/plugins As noarch packages can be built on any machine/architecture in koji, we'd end up with lib64 directories on 32bit archs Here is the list of offending packages I've found: Package Owner ------------------------ ntfs-config laxathom firstaidkit msivak terminus-font ndim gdeskcal pfj libopensync-plugin-synce awjb cohoba tjikkun gnome-schedule farnold common-lisp-controller green gcstar tian revisor-cli jsteffan jruby konradm Can we make it a policy to not use _libdir or _lib in noarch packages, please ?
