GCC is surprisingly simple to build, fortunately.

Yeah it’s not too bad, but it does pull away from “so trivial it fits in a flippant HN comment”

Does it? Admittedly, it has been a while but I don't remember it differing too much from the good old ./configure && make paradigm with a few flags to both commands.

It’d fit in a comment, but not a flippant one ;)
