Thanks again Richard.

So stepping back to 10,000 feet, we now need to specify options and ISA's we
are not using. That seems like a bug to me. I'm not sure I would consider this
fixed.

Where is it going to stop? How many non-used options that I am not aware of
will I need to specify?

I think either GCC or Debian needs to fix this. This could be a GCC bug because
GCC apparently knows there's a fp unit but it chooses to ignore it. Instead it
wants me to say it again. This could be a Debian bug because they need to
completely (not partially) configure things.
