kompose fails to build on ppc64 and ppc64le arches due to old sys/unix vendor package

[sinnykumari]

Hi,

Kompose-v0.4.0 fails to build on ppc64(le) architectures with following error message:
# github.com/kubernetes-incubator/kompose/vendor/github.com/fsnotify/fsnotify
src/github.com/kubernetes-incubator/kompose/vendor/github.com/fsnotify/fsnotify/inotify_poller.go:48: undefined: unix.Pipe2

It seems that vendored sys/unix package is old because /vendor/golang.org/x/sys/unix/syscall_linux_ppc64x.go doesn't contain definition of function Pipe2 for ppc64x while upstream has the fixes available golang/sys@b776ec3#diff-ed5775d43461429a9a5247567c3c9fd9R117 .

I built locally and in koji by replacing /vendor/golang.org/x/sys/unix content with https://github.com/golang/sys/tree/master/unix/ and it builds successfully.

I tried to update sys package in kompose using "glide get golang.org/x/sys/unix" , didn't use glide up because glide.yaml doesn't have entry for sys/unix . It doesn't seem to go successfully for me, details are at https://paste.fedoraproject.org/paste/nPuAB0vbRIXDwIqyA0YWE15M1UNdIGYhyRLivL9gydE=

ping @kadel @surajssd - this is why we can't get 0.4.0 out into Fedora right now. It looks like we need to update golang.org/x/sys/unix to latest version.
