If you need a recursive target that is not one of the targets known by
automake, you will need to define a recursive rule yourself, sorry.
In this case however, you may want to use the 'check' target, though,
look at the documentation.

This just states that the target examples depends on some directories
being present.

Use something like:
recursive-target:
$preorder_commands
for dir in $(SUBDIRS); do \
cd $$dir && $(MAKE) $(AM_MAKEFLAGS) $@ || exit 1; \
done
$postorder_commands
.PHONY: recursive-target
(or the slightly more involved scheme that automake itself uses).

Please note that DISTCLEANDIRS has no special meaning to automake.

Usually there is no need to defined DIST_SUBDIRS yourself (it defaults
to $(SUBDIRS)).

If you do this, then all outputs get linked as shared objects, which
would be wrong for programs. I suggest putting -shared into per-target
link flags (lib*_LDFLAGS), or, more portably, using libtool.
Hope that helps.
Cheers,
