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.
