Error: tmp/.config-package.in:xxxxxx:error: recursive dependency detected!

When generating the .config from a diffconfig file, lots of errors were seen, and the build kept failing randomly at different packages.

$ cp r7800.diffconfig .config && make defconfig

Reproduce the report with r7800.diffconfig by copying it to .config and running make defconfig. Inspect the generated tmp/.config-package.in entries for schroot, autopart, cryptsetup, cryptsetup-ssh, integritysetup, and veritysetup, then consult Documentation/kbuild/kconfig-language.rst under “Kconfig recursive dependency limitations.” Done means defconfig completes without recursive-dependency errors.
