  # Arch Linux normally does not enable SSE2 for i686 because of older CPUs.
  #
  # However, exceptions are made for:
  #  * Chromium, which is not expected to be used on older i686 CPUs
  #  * Julia, which requires SSE2
  #
  # Go is so slow that it is unusable on i686 when SSE2 is not enabled, so I am
  # also making an exception for Go.
  #
  # If you really want to build Go without SSE2 support, just uncomment the
  # following export and rebuild:
