I don't think that's supported at all. I have successfully used this
VeryUglyHack(TM) in the package's Makevars:
OBJECTS=dummy.o real1.o real2.o
dummy.o: myExtraTarget
echo "" > dummy.c
$(CC) $(ALL_CPPFLAGS) $(ALL_CFLAGS) -c dummy.c -o $@
where real1.o and real2.o are real object files that have
corresponding sources and dummy.c is a non-existent file thus forcing
make to use my extra target. This hack exploits the fact that SHLIB
will let Makevars override the objects list (the above is not the
exact application I use, but the essence of the idea).
I agree that it would be great to add something like $(EXTRA_TARGETS)
to SHLIB such that Makevars can define extra targets.
Back to your original problem, though, I never build packages
directly from development sources (didn't we have a discussion about
this recently?) for the reasons discussed - IMHO it's much better to
have a script build the package tar ball, stamping files as necessary.
Cheers,
Simon
