I still don't understand this discussion. Floats aren't used in u-boot, 
so why should it make a difference if -msoft-float will be removed? I 
know there was one bug which linked in something wrong from glibc, but 
if that flag isn't needed than it shouldn't make a difference at all if 
-msoft-float or -mhard-float is used.

So whats the reasoning to use -msoft-float as it is currently done? To 
confuse people? ;)
