Ideally we would never have a family and BSP variant have the same name.
But that rule is violated multiple times now.

I am not sure where your triple is intended to be used but we have used
the pattern arch/BSP which is really <arch>/<bsp_variant> as the
full name of BSPs.

If we want to step that further, we could do something similar to the
GNU target triple where the middle component is a rarely used vendor.
<arch>/<bsp_family>/<bsp_variant>.

In recent history, there was an issue of BSP variant names needing to
be unique across all architectures. This may also need to apply to bsp
family names.
