I think we need to be able to explain this. It's an increase of over
60%, I wouldn't expect that to be due to the relative ineffiiciency of
Intel instruction encoding over AMD.  And it is not due to the
inclusion of libsylkrts (it's much easier to say "Intel library", how
many other libraries are there in GCC that were written by Intel?)
because that is not in the stage1 bootstrap.
