From: Matthias Kretz <kretz@kde.org>

This is necessary to avoid failures resulting from PR98834.

libstdc++-v3/ChangeLog:
	* testsuite/Makefile.am: Warn about the workaround. Add
	-fno-tree-vrp to CXXFLAGS passed to the check_simd script.
	Improve initial user feedback from make check-simd.
	* testsuite/Makefile.in: Regenerated.
