T without 68881?

[mark@mcc.com (Mark Scheevel)]

We cannot get T to run on our Sun 3/50 machines because they do not
have 68881 co-processors.  I tried the simple-minded approach of
recompiling tsystem/float.c with the -fsoft option and then re-linking
(i.e., system-suspend of the existing system followed by linkt with
the new float.o), but that didn't do the trick.  Do I have to rebuild
the entire system (shudder!) just to get a version with soft
floating-point?  Or is there some simpler way?
