Add the Faccessat, Fchownat, Linkat, Mkdirat, Openat, Readlinkat, Renameat, Symlinkat and Unlinkat functions (to conform to POSIX.1-2008) and make Fchmodat available on all architectures, not just amd64. Also add the missing AT_* constants. Generated on Mac OS 10.11 (Darwin 15.6.0) for darwin/amd64 and darwin/386 only. Fixes golang/go#14458 Change-Id: I6d9258864383ea77f9cad058ee8ba2c728213b40 Reviewed-on: https://go-review.googlesource.com/50450 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>
