    debug/readlink{, at}_chk.c: Harmonize declaration and definition
    
    The declaration and definition of these routines aren't consistent.
    
    Make the definition of __readlink_chk and __readlinkat_chk match the
    declaration of the routines they fortify.  While there are no problems
    today this avoids any future potential problems related to the mismatch.
