I've looked at these.  Most of them do not have a `html:' rule.
They seem to reuse a Makefile.am that apprently comes from GTK+
and which uses dir.stamp tricks like the one shown earlier in
this thread.  

gnome-libs/devel-docs's Makefile.ams use a PHONY `html:' rule
already.

In both cases, what we do is harmless.

 Ralf> ./ncurses-5.3/doc/html

No html rule.

 Ralf> ./Python-2.2.1/Doc/html

Python is an exception, as it has a recursive `html:' rule which
isn't marked PHONY.  I don't really understand why it isn't
PHONY, but marking this rule PHONY doesn't seem harmful, as
their `mkdir' is already protected by a `test -d'.  Python
doesn't use Automake anyway :)
