Alright, I have opened both 

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94193
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94194

And updated the commit message locally to reference it.

For the m68k case I think moving the required macros from
mathinline.h to mathimpl.h should enable the build (and it
should make Os work as well).
