b52fc2d fix the build error it cause runtime segfault.

I wonder did  you test b52fc2d .  my quick test show a segmentation fault at 
pluto shutdown. 

Program terminated with signal SIGSEGV, Segmentation fault.

Line 1921         kernel_ops->shutdown();

This what satarted ths commit race:
cagney: with USE_XFRM_INTERFACE=false https://travis-ci.org/antonyantony/libreswan/builds/654227133  kernel_xfrm.o:(.data.rel.ro+0x30): undefined reference to `free_xfrmi_ipsec1'  

missing ifdef. I fixed it
wait it shows up as tuomo fixed it?
weird. git made up the name, or did you just push the exact same patch and commit message?

--- my 0.00 comment.
Just a hint if it helps:
        .shutdown = free_xfrmi_ipsec1,
       .shutdown = NULL

= NULL will caause seg fault.
You need stub like Andrew added for BSD kernel_bsdkame.c c57088adef

Then comes the question where, which file, to add such a stub for xfrm.  
USE_XFRM_INTERFACE=false kernel_xfrm_interface.c is not compiled.
you could possibly add kernel_xfrm_interface.h need test it works or in
