The problem here is that we don't have any Config.in options for
binutils versions, so should this problem be fixed one day, we would
have no way to update this Config.in option.

To be honest, I am starting to wonder if we should keep support for
OpenRISC. It's using a now quite old gcc version, and I'm not sure the
OpenRISC support has been upstreamed to gcc.

Also, we don't have anyone specifically interested in OpenRISC and
maintaining it...
