The change has been reverted shortly after the initial commit to allow for more discussions. This is why the bot is green. You can see that the asan library is being built if you choose "Console Output" menu and click "full log", search for "libclang_rt.asan_osx_dynamic.dylib".

I don't think there is a specific reason why we need the sanitizers to be built with autotools. I agree that the current setup is broken in several ways and needs attention. Thank you for the suggestion to run cmake from an autoconf/Makefile setting; we'll investigate if that could be an acceptable solution.
