That's why I keep a gcc patch around to be able to build 68020 code
without FPU, mainly to target standard Falcon without FPU.

I understand why Vincent would not put it in his gcc patch, as it would
mean 8 multilib configurations (68000,68020,68020-60,m5475, each
with/without mshort) when building gcc. This is not a problem for me,
as I build cross-compilers; it's done fast on my PC, and I have
plenty of hard disk space.
