Log:
  MFC r212570:
  
    Allow a kernel config to specify a set but empty value via
    'makeoptions OPTION=' for consistency with the make commandline.
  
    Previously 'makeoptions WERROR=' would result in a syntax error; now
    it produces the same effect as 'makeoptions WERROR'.  Both forms now
    result in 'WERROR=' in the generated Makefile.
