I've noticed that during kernel compilation '-mno-fpu' flag is set. My 
Ultra10 has 440MHz UltraSparc IIi cpu, which I'm sure has a built-in 
FPU. Is it a good idea to tweak the Makefile to remove '-mno-fpu' so 
that native hardware floating point instructions are used or kernel does 
not use float and double datatypes?
