libatomic is currently unconditionally built with -Werror. This patch adds
--enable-werror to control it (enabled by default). Bootstrapped and tested
on x86_64, and inspected build logs to ensure it was doing what it should.
I'm assuming copyright assignment isn't necessary for a small change like
this. I will also need someone to check this in for me please.

* configure.ac: Add --enable-werror.
(XCFLAGS): Use it.
* configure: Regenerate.
