Yes it could happen and this is where the symmetry and the existing code
matters. For example with `bsps/motorola_powerpc` the code can be easily or
cleanly extended by looking for `bsps` as an arch and knowing that is a
`family`. Otherwise the error is `invalid arch/bsp` and then you need check two
lengths etc etc.
