    ports.7: Fix example of passing variables on the command line
    
    make(1)'s -D flag does not allow for setting the value of the variable.
    It just defines the variable and sets its value to 1. In fact, make(1)
    treats "=" as just another character in the variable name:
    
    ```
    $ make -DA=2 -V A  # Output is just an empty line.
    
    $ make -DA=2 -V A=2  # Variable "A=2" is defined and set to "1".
    1
    ```
