ppc64le: ioctl-sys: error[E0432]: unresolved import this_arch_not_supported

[vt-alt]

JFYI. Build failure on ppc64le with --features full due to some problem in ioctl-sys crate.

I also filed upstream bug codyps/ioctl#29

When building with default features there is no build failure. Perhaps, this is because of local-tun feature included in full.

[zonyitoo]

Yes. It is an known issue. ioctl seems to be abandoned.

I have opened an issue to replace ioctl with nix: meh/rust-tun#87 , but not accepted yet.

Thank you!
