Log:
  switch i386 memstick installer images to MBR
  
  Some BIOSes have trouble booting from GPT in non-UEFI mode.  This is
  commonly reported with Lenovo laptops, including my x220.  As we do not
  currently support booting FreeBSD/i386 via UEFI there's no reason to
  prefer GPT.
  
  The "vestigial swap partition" was added in r265017 to work around an
  issue with loader's GPT support, so we should not need it when using
  MBR.
  
  We may want to make the same change to amd64, although the issue there is
  mitigated by such systems booting via UEFI in the common case.
