Subject:   making -mieee the default

As discussed in the thread "HEADS UP: Don't upgrade your Alphas!",
I would like to make the -mieee option to gcc the default, since
lots of floating point stuff breaks without it.  Alpha hardware
doesn't support IEEE FP, so there is a performance penalty
associated with this; when a floating point value x *might* be
NaN, the compiler inserts explicit logic to generate a trap only
if appropriate.  (It seems to use cmpt??/su most of the time).  I
just wanted to check if there were any objections before moving
forward.
