That's rather dangerous: we have had lots of trouble with packages for
which the Makefile works on the maintainer's Linux, but not on other
people's systems (even Linux ones).
Do you really, really need a Makefile.win?: I would be surprised if you
did. Only 9 CRAN packages have a Makefile.win, and two of those are
dummies and one other we have asked the maintainers to replace by
Makevars.win as it is not portable.

Adding the resources is not essential: they add identification to the
DLL which can be very useful but are icing on the cake. So I would not
try to emulate that step.
But the Makefile in use is src/gnuwin32/MakeDll and that contains
$(DLLNAME)_res.rc:
@PERL5LIB=$(RHOME)/share/perl $(PERL)
$(RHOME)/src/gnuwin32/makeDllRes.pl $(DLLNAME) > $@
$(DLLNAME)_res.o: $(DLLNAME)_res.rc $(RHOME)/include/Rversion.h
