Enable -Wstringop-overflow globally

Browse source 
Hi Linus,
 
 Please, pull the following patches that enable -Wstringop-overflow,
 globally. These patches have been baking in linux-next for a whole
 development cycle.
 
 I waited for the release of -rc1 to run a final build-test on top of
 it before sending this pull request. Fortunatelly, after building
 358 kernels overnight (basically all supported archs with a wide
 variety of configs), no more warnings have surfaced! :)
 
 Thus, we are in a good position to enable this compiler option for
 all versions of GCC that support it, with the exception of GCC-11,
 which appears to have some issues with this option[1].
