That's been just 4-5 mails so far. This is *far* from being a lengthy
discussion, especialy by Buildroot standards! ;-]

Alternatively, you can use a br2-external tree, with:

  - Config.in is empty

  - external.desc contains:
        name: LEGAL_IN_TARGET
        desc: Isntall legal-info in rootfs

  - external.mk contains something like:
        target-finalize: legal-info

        TARGET_FINALIZE_LEGAL_INFO_DIR = $(TARGET_DIR)/usr/share/legal-info

        define TARGET_FINALIZE_LEGAL_INFO
            $(INSTALL) -D -m 0644 $(LEGAL_MANIFEST_CSV_TARGET) \
                $(TARGET_FINALIZE_LEGAL_INFO_DIR)/$(notdir $(LEGAL_MANIFEST_CSV_TARGET))
            mkdir -p $(TARGET_FINALIZE_LEGAL_INFO_DIR)/licenses
            cp -a $(LICENSE_FILES_DIR_TARGET)/* \
                $(TARGET_FINALIZE_LEGAL_INFO_DIR)/licenses/
        endef
        TARGET_FINALIZE_HOOKS += TARGET_FINALIZE_LEGAL_INFO

I've slightly tested that, and it seems to be working...
