Implement --enable-sanitizers[=sanitizers]
Similar to debugging with Valgrind, it's very useful to enable
-fsanitize= switches to catch bugs at runtime.
$ ./configure
Result: no sanitizer enabled
$ ./configure --enable-sanitizers
Result: -fsanitize=address,undefined
$ ./configure --enable-sanitizers=address,thread,undefined
Result: -fsanitize=address,thread,undefined
$ ./configure --enable-sanitizers=undefined
Result: -fsanitize=undefined
