tests fail on s390x

[carlwgeorge]

Hello! I'm packaging this library for Fedora, and I noticed that the test suite fails on s390x. I'm not using this architecture myself, but it is one of the architectures that Fedora builds for.

error

I tried this outside of the go packaging macros, and it still failed, albeit with a slightly different error.

$ go env | grep -e GOOS -e GOARCH
GOARCH="s390x"
GOOS="linux"
$ go get github.com/ovh/go-ovh/ovh
$ cd go/src/github.com/ovh/go-ovh/ovh/
$ go test
fork/exec /tmp/go-build729930756/b001/ovh.test: exec format error
FAIL	github.com/ovh/go-ovh/ovh	0.000s

The same steps pass on x86_64.

$ go env | grep -e GOOS -e GOARCH
GOARCH="amd64"
GOOS="linux"
$ go get github.com/ovh/go-ovh/ovh
$ cd go/src/github.com/ovh/go-ovh/ovh/
$ go test

Updating to 1.1.0 on Rawhide, the issue does not present itself anymore.
I think this can be close.
