I am not sure. My initial reaction was "yes" but how would different settings
for a BSP and a family be handled? I am assuming a BSP variant setting is able
to override a family setting. Is that possible if they are merged?

Oh I think my patch piece may have been wrong. This has two `/` and so three
components. We _must_ have unique family names and so the arch part is not
really needed. My concern is this type code ...

https://git.rtems.org/rtems_waf/tree/rtems.py#n758

that breaks. Is this an issue? I think a single `/` in a BSP or family is 
cleaner.
