It would be extremely easy technically.  The preconfigure fragments can 
implement whatever mapping they choose from configure tuples to 
base_machine and machine values - mapping i[4567]86 to x86-32 would be no 
different from mapping them to i386 as at present.  (I'm not saying that 
we *should* rename, just that it would not introduce any new technical 
complications.)
