Before:
  Save g:ale_make_checkmake_config

  Restore

Execute(checkmake should run with default format option):
  let b:command_tail = ' --format=' . b:format . ' %s'

  AssertLinter 'checkmake', 'checkmake' . b:command_tail

Execute(checkmake command should take the config option if it is non-empty):

  let b:command_tail = ' --format=' . b:format
  \ . ' --config="' . g:ale_make_checkmake_config . '"'

Execute(the local buffer config option takes precedence over global option):
