Log:
  Revert r314669, r314670:
  Bring back the i486 option in GENERIC by default.
  
  The code related to i386 CPU variants configuration has received many
  changes in the last years: most of the features are detected automatically,
  so there are no performance penalties from keeping the 486 support enabled.
  
  Re-instate the 486 support: while the general configuration could still be
  cleaned a bit, there is no advantage in removing it.
