#      of configs in the calling code take into account the core_config_add and
#      core_config_remove lists above. So you don't need to manually take these
#      into account: just modify the configs as normal for target-specific
#      overrides (or don't touch it).
#
#   deps
#      Normal meaning but "core:prerequisites" target is always added. Callers
#      shouldn't list prerequisites as a dependency.
#
#   visibility
#      Normal meaning if defined. If undefined, defaults to everything in core.
