Use -Werror for all kernel configure tests.

Browse Source 
As a matter of fact, we're already using -Werror for most tests because
of a bug in kernel-bio-empty-barrier.m4 which sets -Werror without
reverting it afterwards. This meant that all tests which ran after this
one was using -Werror.

This patch simply makes it clear that we're using -Werror and makes
the code more readable and more predictable.
