Gruntfiles are javascript so it needs to be valid javascript, such as:

karma: { 
  unit: (function() { 
    if (grunt.option('Release')) {
      return {};
    } else {
      return {
        configFile: 'build/karma.conf.js',
        singleRun: true,
        browsers: ['PhantomJS']
      };
    }
  }())
}
