OK, according to your specs file, everything should be defaulting
to 68020, so I don't know why the assembler is being called
with the 68000 flag.  There is one place in your specs file that
looks suspicious though:

*predefines:
-Dmc68000 -D__embedded__ -Asystem=embedded   -Amachine=mc68000

Can you do the following for me?

(1)  Edit your specs file so that you change the predefines section to:
-Dmc68020 -D__embedded__ -Asystem=embedded   -Amachine=mc68020

(2)  Try to recompile the offending C++ file, and see if the assembler
is invoked with the 68020 flag.

If that works, then the following patch might be required:
