helping golang-golang-x-sys to migrate

[Reinhard Tartler]

Another week has passed, and the original issues seem to have been resolved
by retrying. Thanks for everyone involved in that.

In the mean time, a new test regression occurred at
https://autopkgtest.ubuntu.com/packages/victoriametrics/hirsute/amd64, log
can be seen at
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-hirsute/hirsute/amd64/v/victoriametrics/20210107_084114_85c06@/log.gz

I suppose the testsuite is running on a machine with only 2 CPUs and
expects more ressources? I've retriggered the test but I'm concerned this
excercise might be a waste of resources. Does anyone share this concern
and/or has any thoughts on how to avoid this?

Best,
