I am open to proposals, but it's you guys (the actual m68k-rtems users)
who need to tell me which multilib versions would be really useful.
We currently have:
# m68k-rtems4.8-gcc --print-multi-lib
m68030/msoft-float;@m68030 at msoft-float
m68040/msoft-float;@m68040 at msoft-float
m68060/msoft-float;@m68060 at msoft-float
Which of them can be removed and which do you think are missing?
