[PATCH] testsuite: XFAIL bogus g++.dg/warn/Wstringop-overflow-4.C:144, PR106120

[Hans-Peter Nilsson]

(sort-of-ping:) Aldy, I missed CC:ing you on the similar
https://gcc.gnu.org/pipermail/gcc-patches/2023-February/611206.html
would you mind having a look?

Tested native x86_64-pc-linux-gnu (w/wo. -m32) and cris-elf.
Ok to commit?

---- 8< ----
There was a commit r13-2082-gbf13a13c65bd06 "c++: remove some xfails"
(not referencing the PR) that dealt with part of the PR, but didn't
xfail the ilp32-specific (bogus) warning mentioned in the PR.

	PR testsuite/106120
	* g++.dg/warn/Wstringop-overflow-4.C:144 XFAIL bogus warning for
	ilp32 targets with c++98.

Up to the release managers, but I have no objections.

I take it that's for both patches.  Thanks!
(Potential reviewers: these patches are local to the testsuite.)
