Subject: [PATCH v2 12/14] selftests/nolibc: add tinyconfig target

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.
