It is correct behavior.

You can't comment out things in the middle of scripts like this.
That is not a make comment, because make doesn't process command script
lines in any way except for expanding make variables. That includes not
doing any comment processing (obviously, since in order to do this
properly make would have to understand full shell syntax to know when
the comment char was quoted or whatever).
Since the previous line ends in a backslash, the next line is appended
to it and make treats the whole thing as part of the single command
line.
And, if you write all that out without any backslashes you'll see that
it resolves to this:
<...> fi ; echo <...> | sh -x ; # chmod <...>; done
When the shell sees that comment character, it stops processing, so your
loop is missing its "done" (it's commented out).
You're not allowed to put comments in continued lines like this, it
almost never does what you want.
One option would be to prefix the command you want to avoid with the
shell's no-op command, ":". Change this:
fi ;\
echo $$rcp $$temp $$host:$(DESTDIR)/$(FILE) $$close | sh -x
;\
# chmod $(MODE) $(DESTDIR)/$(FILE) ;\
done
to this:
fi ;\
echo $$rcp $$temp $$host:$(DESTDIR)/$(FILE) $$close | sh -x
;\
: chmod $(MODE) $(DESTDIR)/$(FILE) ;\
done
See the shell man page for more details.
