  Log:
  Remove the CPU_ENABLE_SSE option from the i386 and pc98 architectures,
  as they are already default for I686_CPU for almost 3 years, and
  CPU_DISABLE_SSE always disables it.  On the other hand, CPU_ENABLE_SSE
  does not work for I486_CPU and I586_CPU.
  
  This commit has:
          - Removed the option from conf/options.*
          - Removed the option and comments from MD NOTES files
          - Simplified the CPU_ENABLE_SSE ifdef's so they don't
            deal with CPU_ENABLE_SSE from kernel configuration. (*)
  
  For most users, this commit should be largely no-op.  If you used to
  place CPU_ENABLE_SSE into your kernel configuration for some reason,
  it is time to remove it.
  
  (*) The ifdef's of CPU_ENABLE_SSE are not removed at this point, since
      we need to change it to !defined(CPU_DISABLE_SSE) && defined(I686_CPU),
      not just !defined(CPU_DISABLE_SSE), if we really want to do so.
