If your intention is to make -Werror the default please stop.
Defaulting WERROR to enabled is one of the silliest things we have done
in recent past.

People will try to use new compilers on a kernel after it has already
been released. Not being able to build the kernel because of some false
positive warning in another subsystem is so annoying :|
