Thanks! I tried that before, but without ':' before '=':
semctl08: LDLIBS = -lltpnewipc $(LDLIBS)
Makefile:12: *** Recursive variable 'LDLIBS' references itself (eventually).  Stop.

Assigning as := fixes that:
-semctl08: LDLIBS += -lltpnewipc
+semctl08: LDLIBS := -lltpnewipc $(LDLIBS)

Sorry for overlooking obvious error.

Are you're going to fix by changing order somewhere in include/mk/?
Or shell I push the fix with your ack?
I'd prefer proper fix so commits like this or 22f510de8 ("Fix static linking
with musl-fts") aren't needed any more.

Kind regards,
Petr
