Here I'm confused. Top-level Makefile never does (cd Doc; make zsh.texi); it
does all, install, clean ... but never subdir-specific targets.

So, we need zsh.texi in source dir to include it with distribution (for
users without yodl). Right?

I suggest to use placeholder like texi, dvi, html etc as main targets and
make them depend on actual files. Like

all: man texi

man: $(MAN)

texi: $(sdir)/zsh.texi

That is what e.g. bash does.
