Someone needs to make a judgement call and either fix all these Kconfig entries or document that MEDIA_SUBDRV_AUTOSELECT will let you shoot yourself in the foot at build time. Then what I recommend in the meantime is simply to not trust randomconfig builds unless you are always enabling MEDIA_SUBDRV_AUTOSELECT. I think its fair to expect for 'make randomconfig' to give you a configuration that lets you build things without issue so I see this more of an issue with MEDIA_SUBDRV_AUTOSELECT and this sloppy embedded craze.
