I was able to reproduce this with cargo xbuild --target x86_64-unknown-dragonfly. For context, we attempted to get errno working correctly on DragonFlyBSD via rust-lang/libc#1432 but that only allows it to work when libc is a dep of libstd. The is because:
- DragonflyBSD (unlike every other UNIX target) uses a thread-local static variable directly for its errono (as opposed to going through a helper method like
__erroror_errno_locaiton. - Rust thread-local statics are not stable, see rust-lang/rust#29594
So we will probably just not bother with getting errno information on Dragonfly, which should fix the issue.
