indeed, just like MIPS/ECOFF.  That's my point about those removals: if
there isn't a current version of GCC to support the targets, keeping
binutils support doesn't buy anyone a thing, not even the enthusiasts
that keep those machines alive.

One might include those targets in config.bfd's list of obsolete targets
on the 2.35 branch so potential remaining users get prominent notice
about the removal.  Than at some point during the 2.36 cycle they could
be removed unless someone steps up to do the maintenance.
