Thanks, committed. This went unnoticed during review of recent diff.git
changes. I will patch up the devel/got port as well to make it allow
it to build on OpenBSD/sparc64.

It would be nice if someone could run util/got-build-regress.sh on
a sparc64 machine once per day. That would have caught this problem
weeks ago. I used to do this but I no longer have any sparc64 left.
