I think using equiv-* for this is not correct.

Hosts named equiv-* are supposed to be completely identical, but we
might end up with hosts which are similar enough that they qualify for
this cross-architecture testing, and but not completely identical.

Furthermore, using equiv-* makes it difficult to automatically search
for a list of the different board classes we would want to use.

I would invent a new prefix.  Perhaps flags like

Then you could search the database

  SELECT UNIQUE platform
     SUCHTHAT (host,"arch-$arch") in hostflags
          AND (host,"blessed-$whatever") in hostflags

rather than hardcoding the list in make-flight.

See above.  `equiv-marilith' would be correct if we had another
identical Calxeda box.
