One straightforward way to do this, at the cost of a recursive
invocation of make, is something like:

        all: main-real
        main:
                @$(MAKE) -o libraries main-real
        main-real: <real "main" target stuff>
        libraries: <libraries target stuff>

It needs a little work to get the rebuild stuff down (when to rebuild
and when not to).
