build: disable bogus warnings for GCC 12
The array bounds and string overread check on GCC 12 report a dozen of false positives that result in VPP build failures on ubuntu 22.04. Work around this build issue by unconditionally disabling these two warnings if C compiler is GCC 12 or newer version. Type: fix Signed-off-by: Jieqiang Wang <jieqiang.wang@arm.com> Change-Id: I999e847bb625ebdf3ef5f11b11598c553f306670
