re PR testsuite/25318 (g++.dg/other/pr22003.C (test for excess errors) fails)

	PR testsuite/25318
	* lib/target-supports.exp (check_effective_target_freorder):
	Check to see if target supports -freorder-blocks-and-partition.
	* g++.dg/other/pr22003.C: Use "dg-require-effective-target freorder"
	instead of "dg-require-named-sections".
