The configure error mentioned in the commits that disable --with-arch/--with-tune when --with-cpu is specified is specific to ARM builds. For other architectures, it makes sense (hey, it even makes sense for ARM - read 'info gcc'! - it is just a shortcoming of ARM build, apparently). Thus, add an arch setting ARCH_EXCLUSIVE_WITH_CPU (currently, set only for ARM) that will trigger current behavior. Permit combinations of --with-arch/cpu/tune for other arches.
