Remove vestigial local cursor self-reference on FreeBSD
Commit debb6128d17b782552d53efa8869a392d1f40a83 removed the
self-reference from the cursor on x86_64 but only did so on Linux;
FreeBSD was still relying on being able to self-reference. This commit
applies a change to FreeBSD analogous to that made on Linux.
