Auto-detecting would be quite complex as it would need to take into
account processing the configs in u-boot before being able to know
whether to add the dependency or not. Making this user configurable
via PACKAGECONFIG might add additional confusion, especially since it
is not a dependency of the target output.

Please keep in mind, openssl-native is already dragged in by other
dependencies in order to build u-boot (e.g. rpm-native which is added
to all recipes inheriting package.bbclass regardless of
PACKAGE_CLASSES). Also if you are using u-boot it is likely that you
are depending on u-boot-mkimage-native as it is used for kernel image
and/or rootfs image packing.
