Please, drop this patch.

Never enable -Werror unconditionally for any part of build.

I often bisect Linux. And to do this, I often need to build very old
Linux commits (with modern compiler). Unconditional -Werror will make
this impossible.

For example, recently I found this regression:

https://lore.kernel.org/regressions/197f290e30b.eaadc7bc7913.7315623184036672946@xxxxxxxxxxxx/T/#u

The regression caused by commits happened in 2019.

So to bisect it, I had to build 2019 trees using modern compiler.
