yes, read /usr/src/UPDATING.

20010803:
  (i386 only): i386 kernel now uses new instructions like
        `fxsave' which old gas doesn't understand.  To build the
  kernel successfully, you need to build and install new gas
  (gnu/usr.bin/gas.new), or (temporarily) comment out
  "options I686_CPU" from your kernel configuration until you
  rebuilt your userland (and got a new gas).
