-Werror is a bit user hostile, it can be incredibly irritating when
you're debugging things to get things like unused variable warnings from
your debug code or to be working with an unusual config/arch that throws
up warnings that aren't normally seen.  A clean build doesn't require us
to enable -Werror, it requires us to pay attention to warnings.
