cc @asomers in case you want to review - otherwise, @semarie if this doesn't break anything on our end, and it works for OpenBSD, i'm fine with it.

My only request is for you to add this particular target to ci/build.sh at some point to make sure that this target at least builds correctly.

@gnzlbg hey. I missed the addition in ci/build.sh. It should be fine now.

@gnzlbg I see style-and-doc test failed because the target is unknown. should I postpone the inclusion of sparc64-unknown-openbsd for after support was added to rustc ?

[gnzlbg]

You can comment it here for now, and uncomment it once you have added a rustc_target specification for the target. Ideally there would at least be a PR for that before merging this.

I removed the commit adding openbsd-unknown-sparc64 in ci/build.sh. Commenting wasn't a solution as it was a part of a shell variable. It will be readded later.

Waiting the PR in rustc is possible, but I expected to do one PR in rustc, and not one for the target and another for updating libc. I am preparing a PR for rustc.

I trust you on this, you have done this before.
