The problem is, since 614581f32b domaincapstest is linked with
$(LDADDS) by default. Then, since 94e3f23e8a7 the test may be
conditionally linked with $(qemu_LDADDS) which already contains
$(LDADDS). And some linkers doesn't cope with this nicely:
CCLD     domaincapstest

../src/libvirt_probes.o:(.probes+0x0): first defined here

../src/libvirt_probes.o:(.probes+0x6): multiple definition of `libvirt_event_poll_dispatch_handle_semaphore'
../src/libvirt_probes.o:(.probes+0x6): first defined here
And so on.

I'd push this as build breaker, but there's another approach to consider,
create qemu_BARE_LDADDS and fill it with the qemu_impl, etc. Then, let:
qemu_LDADDS = $(qemu_BARE_LDADDS) $(LDADDS)
What's your preference?
What is below works for me - so to that degree I'd ACK.  However, if
someone had a preference for whatever it is you're describing as an
option, then I suppose that would be fine too.  Makefile's are mostly
black magic to me :-)
