 As a developer maintaining a multisite network, I'd like to prevent super
 administrators from enabling any administration menus on individual sites,
 such as "Plugins." I can do this with:

 `add_filter( 'mu_menu_items', '__return_empty_array' );`

 However, the `Menu Settings` heading and empty settings table still appear
 on the Network Settings screen. See the attached screenshot.

 The attached patch would check for available menus after applying
 `mu_menu_items` and before rendering the markup.
