make -j8 and .END

["Simon J. Gerraty" <sjg%crufty.net@localhost>]

It is very handy to be able to accumulate dependencies for targets
like .BEGIN and .END.  Our make has supported this for quite some
time.  Turns out though, that a makefile like:

all bye:
        @echo $@

.END: bye

doesn't work with -j, though it works as expected without.

$ make -f /homes/sjg/make-tests/end
all
bye
$ make -f /homes/sjg/make-tests/end -j2
--- all ---
all
$

the patch below fixes that.

--sjg
