4981 - no, go back to 3 phases
Considering how much trouble a merge phase would be (commit 4978), it seems simpler to just add the extra syntax for controlling the entry point of the generated ELF binary. But I wouldn't have noticed this if I hadn't taken the time to write out the commit messages of 4976 and 4978. Even if we happened to already have linked list primitives built, this may still be a good idea considering that I'm saving quite a lot of code in duplicated entrypoints.
