In that case it is the input that is wrong:

    Some macros are predefined on each kind of machine
    (@pxref{System-specific Predefined Macros, System-specific Predefined
    Macros, System-specific Predefined Macros, gcc, Using the GNU Compiler
    Collection}).  This allows you to provide code specially tuned for a
    particular machine.

It should be

    Some macros are predefined on each kind of machine
    (@pxref{System specific Predefined Macros, System specific Predefined
    Macros, System-specific Predefined Macros, gcc, Using the GNU Compiler
    Collection}).  This allows you to provide code specially tuned for a
    particular machine.

changing the hyphen to a space in "System specific".
