[PATCH v1 1/1] Makefile.extrawarn: Turn off -Werror when extra warnings are enabled

When `make W=1 ...` is executed the level 1 warnings become errors,
due to recent change in some of the defconfigs, and fail the build.
Since there are a lot of warnings on the level 1 are still present
in the defconfigs at least for x86, let disable -Werror in such case.

Fixes: b9080ba4a6ec ("x86/defconfig: Enable WERROR")
