Some strncat tests fail to build with GCC 8 because of -Warray-bounds warnings. These tests are deliberately test over-large size arguments passed to strncat, and already disable -Wstringop-overflow warnings, but now the warnings for these tests come under -Warray-bounds so that option needs disabling for them as well, which this patch does (with an update on the comments; the DIAG_IGNORE_NEEDS_COMMENT call for -Warray-bounds doesn't need to be conditional itself, because that option is supported by all versions of GCC that can build glibc). Tested compilation with build-many-glibcs.py for aarch64-linux-gnu. * string/tester.c (test_strncat): Also disable -Warray-bounds warnings for two tests.
