I (finally) have a patch to fix the build on FreeBSD/amd64 (and probably
FreeBSD on other platforms) here:

https://github.com/bsdjhb/gdb/commit/e58a36eaef6244d2040ce6f377497ee898978db4

It's a combined patch but has some commentary on bsd-kvm.c which is
kind of special.  That target adds new commands that need to find a
target to operate on.  I opted to have it look at the current inferior
and if (using a dynamic cast) it is a bsd-kvm target the commands
modify the state of that inferior.  I haven't tested it though as I don't
use bsd-kvm.c.

I did try a simple test of creating two inferiors both of which were
running /bin/ls and gdb hung trying to run the second inferior via
'start'.  I suspect this is some kind of bug in the FreeBSD target not
being multi-target ready that I will have to debug.
