Turn off CONFIG_HYPERV - neither needed nor supported (but the failure
mode is indeed unfortunate).

In general, as you are building a full-featured distro config, you will
likely get much more than you need. And have to wait for that much
longer. I can recommend "make localmodconfig" as alternative.
