It sounds like you are using $(LIBMULTITHREAD) when you should in fact
be using $(LTLIBMULTITHREAD). See the module description:
Link:
$(LTLIBMULTITHREAD) when linking with libtool, $(LIBMULTITHREAD) otherwise
The way things should work when using libtool is in use is that
* libtool does not see any --push-state or --as-needed options, only
-lpthread or -pthread.
* libtool passes these options to GCC.
* GCC inserts the --push-state and --as-needed options.
