snapd 2.51.1+21.10 autotest segfault on ppc64

[Andrea Righi]

I'm getting this error on impish, running the snapd autotest on a ppc64:

# golang.org/x/crypto/ssh
note: module requires Go 1.17
go build golang.org/x/crypto/ssh: /snap/go/7941/pkg/tool/linux_ppc64le/compile: signal: segmentation fault (core dumped)

This doesn't seem to happen on the other architectures and interesting fact, it looks like the module crypto/ssh isn't required.

segfault happens in `go tool compile` process

[Michael Hudson-Doyle (mwhudson)]

This is fixed in the current go snap, current golang-1.16 and golang-1.17 packages and (separately) in the kernel in impish-proposed. So I think this is in hand :)
