Try doing a clean build
This is a fresh checkout.
I can confirm this with mingw32:

A cross build (mingw32 on debian) also results in this linker error.
The reason is quite simple: tap.o (which provides tap_get_vhost_net)
is only build for posix systems, but not for windows:
Makefile.objs:net-nested-$(CONFIG_POSIX) += tap.o
Changing this does not help because tap.c does not
compile for win32 without errors. Either these errors
have to be fixed, or don't call tap_get_vhost_net when
compiling for win32.
