Note the lack of -DMODVERSIONS here. Also, if your kernel is built for
SMP, there must be -D__SMP__ here.

FWIW, it is not a good idea to be compiling stuff as root. We've got
pseudo-user "sources" for compiling the kernel and kernel modules.

So it fails to find even the most essential symbols. My guess is that
you have the kernel built with CONFIG_MODVERSIONS, but you are not
building the module in the same way. You need to either rebuild the
kernel without modversions or build the module with modversions as well.
