Ah, yes of course. This was just because I tried to translate the
existing

  #ifdef CONFIG_PARTITION_TYPE_GUID
    if (!str)

logic as closely as possible. I can resend. However, I plan to send some
followup cleanups and simplifications to env/mmc.c anyway later, but
didn't want to entangle those with this bugfix, so perhaps it can be
done as part of that.
