proposed fix

Let's "make VIMAGE=yes" in sys/modules/ipfw_pmod/ build VIMAGE-enabled kernel module. Now it builds without errors but does not kldload with an error: 

link_elf_obj: symbol layer3_chain undefined

Attached patch fixes this.

I think this problem should be solved in general, because not only ipfw modules are affected with this.

Enable VIMAGE by default

What about something like this? Untested yet.

Looks good.

Sorry for unintentionally adding comment 2, this issue/fix is probably irrelevant to bug 228854, which doesn't appear to be much serious. 

BTW 11-STABLE patched with this ae@ fix builds fine both with and without options VIMAGE.

Just notifying of awaiting PR. FreeBSD12 is affected too.
