Hi,

The softfloat patches had two parts to them.

- make sure that gcc was called with -msoft-float.

- make sure that libc had a full software floating point
package which matched what gcc was expecting.

The second part was stolen from the arm port.

Therefore, if you have the softfloat build installed 
-msoft-float will work just fine.  It works (well used to
work) just fine from build.sh on a non m68k system, so, it
probably still works.

If you don't have the softfloat build installed -msoft-float 
will compile, but not link.

cheers

bruce
