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.
