+Avoid false-positive error in gnulib tests 'test-perror2' and 'test-strerror_r'.

+On openSUSE OBS, the above gnulib tests fail on armv7l.

+    
+    The problem is visible with glibc 2.32 under valgrind:

+
+    I think it's the test that's invalid.
+
+    This was reported as an actual grep test failure (without valgrind) on
+    32-bit Arm, where glibc malloc happens to return a different buffer
+    address for the internal allocation (so that msg3 != msg4).
+
+    test-strerror_r has the same issue.
+
+    Thanks,
+    Florian
