This is very tricky to do. The only way to do it is to have all the
objects for moduleA depend on moduleB.a so that no objects for moduleA
are built until moduleB.a is completed (and the objects are removed).
For example, using your example above and another library moduleB.a that
should be built first, you'd add a line like:
moduleA.a $(moduleA_OBJS) : | moduleB.a
(the "|" marks an order-only prerequisite: see the GNU make manual for
details. You need a sufficiently newer version of GNU make to use this).
