Like this?

.PHONY: help
help:
        @echo "Please see here for a list of standard targets and their"
        @echo "semantics (unless the package author has overridden them):"
        @echo 
"<http://www.gnu.org/software/automake/manual/html_node/Standard-Targets.html>"
        @echo 
"<http://www.gnu.org/prep/standards/html_node/Standard-Targets.html>"

I don't see how to cope nicely with overridden targets.  Note BTW that
the user is not supposed to override them, but it happens nonetheless.

FWIW, I'm not yet convinced this to be all that useful (but I don't have
a strong opinion either way).
