Subject: [PATCH v2 4/5] selftests/nolibc: execute defconfig before other
 targets

Some targets use the test kernel configuration.
Executing defconfig in the same make invocation as those targets results
in errors as the configuration may be in an inconsistent state during
reconfiguration.
Avoid this by introducing ordering dependencies between the defconfig
and some other targets.
