I'd rather have an automatic mechanism. Can ALL_LOCATE_TARGET be set
automatically to, say, "Solaris2.6", "Solaris2.8" etc. ?

Great.
Here is what I'm currently doing in makefiles:

myprog : mylibtest myprog.o
        $(LINK) -o myprog myprog.o libmylib.a

mylibtest : libmylib.a mylibtest.o
        $(LINK) -o mylibtest mylibtest.o libmylib.a
        mylibtest || { rm mylibtest; exit 1; }

The main trick is that the test program is removed after a failure (i.e.
after it returns with non-null exit code). This ensures that tests are
mandatory, but are only run when out-of-date (this is important for a
big test suite). I've verified that this trick works whith Jam as well.

Ulli
