    testsuite: i386: adapt to -std=gnu23 default change
    
    r15-5327-g55e3bd376b2214 changes the default to -std=gnu23 but this
    test relies on unprototyped functions. Follow Joseph's advice
    in that commit and tweak the test accordingly.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/i386/pr66891.c: Pass -std=gnu17.
