Gah... I missed that... Thanks for spotting! :-)

Yes. With a comment stating so, like:

    config BR2_LINUX_KERNEL_TOOL_SELFTESTS
        bool "selftests"
        depends on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS # bash
        depends on BR2_USE_MMU  # bash
        select BR2_PACKAGE_BASH

    comment "selftests needs BR2_PACKAGE_BUSYBOX_SHOW_OTHERS"
        depends on !BR2_PACKAGE_BUSYBOX_SHOW_OTHERS

(not so nice, but we already have it for openvmtools.)
