Hmm? Are you mixing up nm -g with ld -Map ?

The actual map file is generated by $(LD) -Map <mapfile>, rsp. $(CC)
-Wl,-Map,<mapfile> if invoking the linker via the compiler.

E.g. (from gensh1.cfg - which is what I am using :):

define make-exe
        $(LINK.c) $(AM_CFLAGS) $(AM_LDFLAGS) \
            -Wl,-Map,$(basename $@).map \
            $(LDLIBS) -o $@ \
            $(LINK_OBJS) $(LINK_LIBS)
        $(NM) -n $@ > $(basename $@).num
        $(SIZE) $@
endef
