With current contents of gcc/config/i386/i386.h it doesn't fix problem 
due to bug  (see my earlier post). I should redefine CPP_CPU_SPEC 
to do that.

I think I'll leave rebuilding anyway as one more test for all this stuff
(building gcc) in evening. At first I should fix CPP_CPU_SPEC (it 
defines now __i486__ when -mcpu=i486, etc, but -march should be 
checked instead)
