Yes, in theory default-configs would end up empty, except for possibly
some commented lines to show the "default y" symbols for the target.

--with-device-config=configs/nemu/" to pick up the alternative
configurations.

Yeah, the configure command line is a different story. If there are
suggestion on how to improve it, great, but let's not conflate it with
Kconfig.
