Can this lib support AIX OS and ppc64 ARCH?

[gdtdpt]

I want to cross compile filebeat to GOOS=aix GOARCH=ppc64 environment.
I try to change some libs to the newest which had supported aix platform.
But I got an error from ../vendor/github.com/elastic/go-txfile/internal/vfs/osfs/lock_other.go:39:9: undefined: unix.Flock.
I found that unix.Flock is from golang.org/x/sys/unix and golang.org/x/sys/unix lib has supported aix with the file names zsyscall_aix_ppc64.go.
But there is not Flock function in it and I don't know how to change Flock function to any other functions in zsyscall_aix_ppc64.go.

So I get stuck. Can anyone help me?

I think on AIX you need fcntl to properly lock a file. This requires some more effort. On Windows go-txfile uses the github.com/gofrs/flock package. One could modify the internal osfs package to always use flock, independent on OS, or use it for windows and AIX only. Problem is: the flock package does not implement flock on AIX, but this PR introduces flock support for AIX: gofrs/flock#40
