why is gap-install linked with libgap?

[dimpase]

In Makefile.rules one has

# build rule for the gap executable used by the `install-bin` target
build/gap-install: libgap$(SHLIB_EXT) cnf/GAP-LDFLAGS cnf/GAP-LIBS cnf/GAP-OBJS build/obj/build/main.c.o
        $(QUIET_LINK)$(LINK) $(GAP_LDFLAGS) build/obj/build/main.c.o $(GAP_LIBS) -L${abs_builddir} -lgap -o $@

endif

Does this mean that gap as installed by make install is using libgap, unlike ./gap produced by make ?

And so, in particular, packages producing GAP kernel extensions might need to be linked to libgap (we observe errors on a recent arm64 macOS to this extent).
