According to the comment in softemu8xx.c, the only reason for it was 
that "it was easier than trying to get the libraries compiled for 
software floating point."  Given that soft-float toolchains are easily 
had now, and that full emulation could be used if one really needs to 
work with hard-float binaries, I don't really see the need for this...

If you want to move it over and test it, though, be my guest. :-)
