I just see this one little optimization potential for the dependency declarations, and of course the segfaulting... Else I am ok with proceeding.

Ok, let me try to illustrate this a little clearer. We might want to do the following:
- move `gcoap` dep into `cord_common` (as it is used by all three, `cord_epsim`, `cord_ep`, and `cord_lc`)
- factor out the shared modules that are deps for both `cord_ep` and `cord_lt`, something like this:
ifneq (,$(filter cord_lc,$(USEMODULE)))
USEMODULE += clif
ifneq (,$(filter cord_lc cord_ep,$(USEMODULE)))
USEMODULE += core_thread_flags
USEMODULE += cord_common
ifneq (,$(filter shell_commands,$(USEMODULE)))
USEMODULE += sock_util
ifneq (,$(filter cord_common,$(USEMODULE)))
USEMODULE += gcoap
USEMODULE += fmt
USEMODULE += luid
This way there is not duplicate deps declaration for those modules anymore.

It would still be nice not to duplicate this code, but then again I don't see this as a show stopper for now. So lets postpone this step until after this PR is merged...
