Building randconfig kernels frequently leads to build errors from drivers that have additional build dependencies, or that we don't want to build for compile-testing for some other reason. We already have a couple of compile-time options that can deal with this problem, but the complete set is not documented well. We also have a method to override some options during 'make randconfig' and a couple of other make targets. However, we don't yet combine those two. This adds a new allrandom.config file to turn on CONFIG_COMPILE_TEST, CONFIG_STANDALONE and CONFIG_PREVENT_FIRMWARE_BUILD for all randconfig builds. This in turn disables some other options that we already try to avoid in 'allmodconfig' builds and that make no sense in a general randconfig build. Building with 'make randconfig KCONFIG_ALLCONFIG=1' should now always succeed without warnings on x86 and arm64, aside from recent regressions. Other architectures probably need additional bugfixes.
