Yeah, that's just an automake parsing buglet.

I suppose automake could be enhanced to also define $(OBJECTS) as the
set of all objects.
But there are other ways you could hack around this. Iff your compiler
is generated from a different Makefile.am (this is important!), then in
the tests/Makefile.am you could:
BUILT_SOURCES = stamp-objects
stamp-objects: ../../bin/compiler
-rm -f *.$(OBJEXT)
-rm -f sub/*.$(OBJEXT)
...
echo timestamp >$@
It is rather hacky, but it should work. Untested.
