configure: build with -Werror by default for devel

When building a devel snapshot (eg. a checkout if the repo), build
with -Werror by default, unles overriden by the user. This should
hopefully help catch errors early.

For releases, do not build with -Werror by default, unless the user
explicitly request -Werror.
