At least I can't see why `compile-first` should need to depend on
`compile-zeroth` since the

    %.elc: %.el $(COMPILE_ZEROTH)

rule should already give the same result.
So I'd suggest you drop this part of the patch and see if that causes
any kind of trouble.

I think we can drop the `ifeq` test here.

As for eyeballing: LGTM, thank you.
