svn commit: r310726 - head/sys/boot/i386/cdboot

[Ed Maste]

New Revision: 310726

Log:
  cdboot: add explict suffix to ambiguous or instruction
  
  Clang disallows ambiguous instructions (GNU as has a default based on
  chosen .code setting). We only need 'orb' here because KARGS_FLAGS_PXE
  fits in a byte; this is the same as done in bxeboot.
