I just ran into a build error related to this:

--- libssh.so.5 ---
building shared library libssh.so.5
/local/build/staging/freebsd/wand/obj/arm.armv6/local/build/staging/freebsd/wand/src/tmp/usr/bin/ld: cannot find -lldns
cc: error: linker command failed with exit code 1 (use -v to see invocation)
*** [libssh.so.5] Error code 1

It only happens in one of my many build sandboxes, so I suspect it's
related to the WITH/WITHOUT options in effect and perhaps also to the
timing of parallel-build stuff.  In the sandbox where it fails I have
WITHOUT_KERBEROS and WITHOUT_PROFILE so I think that changes the timing
of getting to the libssh build.

I find that the attached patch fixes it for me.
