FTR: it might take longer than I expected, because for unknown reason Emacs
built with sanitizer isn't built with sanitizer. Yeah, lol. I passed the
`-fsanitize=address,undefined` to CFLAGS, and `./configure …` output even
confirmed it registered them. However, after everything was built, it does not
make use of sanitizer.
I also realised I forgot to pass `-lasan` to LDFLAGS, so the build should've
failed at link-stage. Apparently there are some bugs in the build system
related to passing cflags through to the actual compiler.
