It certainly does no harm to do this -- but when would I want to strip
_native_ binaries with i386-fedora5-linux-strip?

Yeah, that's actually the reason I abandoned the binutils-multi approach
-- since we have to build the separate packages anyway, and the user has
to _install_ the separate packages anyway, I figured we might as well
not be poking around in the _Core_ binutils package to enable all

On the other hand, if Jakub would be happy with --enable-targets=all,
and we switch to generating only gas and ld on the non-native
architectures, that would be a way to reduce the duplication when we end
up with a lot of cross-toolchains installed. It does make the basic
install bigger though, for those who aren't using cross-toolchains. 

I haven't looked recently at how _much_ it bloats the basic install.
