And if we figure that tinyconfig is never called by the user directly but as a dependency from the makefile itself or scripts, then we likely don't even need to create a visible entry for it. Willy

The original tinyconfig target only enables minimal kernel config options, it can speed up the kernel build and nolibc test a lot and also brings us with smaller kernel image size. But the default enabled options are not enough for qemu boot and console print, some additional config options should be added for every architecture individually.
