Hmm, I think the error message is actually coming from the
desktop-file-install program, which is run for the install target in
examples/Makefile.  The rule in the Makefile should be

install install-strip:
        ...
        -if test -n "$(DESKTOP_FILE_INSTALL)"; then \
          $(DESKTOP_FILE_INSTALL) --dir=$(DESTDIR)$(datadir)/applications \
            --vendor www.octave.org octave.desktop; \
        fi
.PHONY: install install-strip

The leading - on the if command here means that any error is supposed
to be ignored, so I'd be surprised if this actually kills the
install.  But if it does, you can fix the problem by removing
this section of the install target rules.  It's not like the desktop
menu info file thing has to be installed for Octave to function.
OTOH, you migth also fix the examples/octave.desktop.in file so that
the desktop install program doesn't complain.  I'm not sure precisely
what change is needed, so it would also help if you (or someone) could
tell us what changes are required to avoid the error.
