Building with -Werror makes a lot of sense for development, but not a

itself enables many extra -W flags. So add a configure flag for distros
to utilize when building.
Please do report any issues you find with -Werror. We explicitly enable
specific -W flags to catch issues. With a modern GNU toolchain the codebase
really should be warning/error free with the default flags. If not, that is
certainly a bug.
For very old setups there is the portable branch and patch set that does
include a --disable-werror option (which you contributed). But in general
that should not be needed.
