Does it need "yes" at the end?
Code:
WITHOUT_LLVM_TARGET_ALL=yesWITHOUT_LLVM_TARGET_ALL=yes
Simple answer: no. The build system only needs the variable up and including the equal sign.
MAKE_JOBS_NUMBERMAKE_ARGS+=-j4OPTIONS_SETIt acts as an override.
Use something like ports-mgmt/poudriere or ports-mgmt/synth to build your own packages with your own options/defaults. Much easier to use.
That's certainly not the case on FreeBSD, the CDDL is compatible enough with the BSD license.

Depends on what you call "optimal" – it picks sane settings known to build without issues and of course using sane compiler optimizations.
CPUTYPE. The benefit of it is questionable as well, but it will be safe. Of course, the drawback is that your binaries won't run on any other machine…On my experimental desktop machine I have only one line in /etc/make.confIt would be nice that experienced users shared their make.conf and src.conf to help new users like me
I know that there are man pages and I read both of them, but real user's configurations are IMHO also helpful!

I'm calling those the most optimal. It's rather pointless to tweak the compiler settings to such an extend you get really small and/or fast code only to have it become utterly unstable or not even run. In my opinion the best settings are already picked by the port maintainer and/or upstream. There's nothing to gain by mucking with those unless you know what you're doing. Most people, including myself, have no idea what most of those compiler settings actually do. So, after 20 years of building FreeBSD and hundreds, if not thousands of ports, I found it's best to leave them alone.
