Except that __FreeBSD_kernel__ wouldn't be included; I'd be surprised
to find LLDB_HOST_BSD true on Debian kFreeBSD.  It's distinct enough
that it would need it's own.

We'll also still need to test for more than one of these in some cases
though -- for example, for socket behaviour that is shared between OS
X and the BSDs.

I think cleaning up these macro tests is a laudable goal, but it's
inherently not possible to cleanly cover all cases.
