It sounds like the alternative is a two step process, generate the
5475 compatible binary first, then generate the 68020-60 libs using
that, yes?

what about one step back and create, m5475-v4e-mint-gcc first, instead
of using m68k-atari-mint-gcc, would that not solve the problem?

This presumes you do not have a v4e to run the final code on..
