Unfortunately that case isn't covered by this patch and D35627. Those patches only address the issue with `-thumb-mode` in the target features.
After thinking about it for a bit I am not sure we can check the case above unless we are fine breaking cases where the default target triple is arm-....., e.g. that `llc -mcpu=cortex-m0 foo.ll` will fail if the default target triple is an "arm" triple.
