I wouldn't think so.

The way to control order would be:

all: foo

foo: bar
     touch $@

bar:
     touch $@

then bar would get built before foo.

When in the presence of "make -jN", and with the following example, I
believe that the order of building "foo" and "bar" is indeterminate.

-------------
all: foo bar

foo:
     touch foo

bar:
     touch bar
-------------

However, is it the case that with this next example, that the order CAN be
determined, and that "foo" would be built before "bar", even in the presence
of "make -jN"?

-------------
all:: foo
all:: bar

foo:
     touch foo

bar:
     touch bar
-------------
