2.1.28 with IPv6 module - missing symbol, Makefile bug

If IPv6 is compiled as a module, csum_partial_copy still needs to be
exported, it was removed in patch 2.1.28. Trivial patch *but* the
net/Makefile does not automatically recompile netsyms.o when netsyms.c
is changed. It is not a timestamp problem, other patches recompile
fine.

I had to rm net/netsyms.o after applying this patch to force netsyms.o
to be recompiled. Any Makefile expert care to say why?
