svn commit: r212570 - head/usr.sbin/config

New Revision: 212570
URL: http://svn.freebsd.org/changeset/base/212570

Log:
  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.
