I only found the culprit today.
I had this lingering in my custom distro layer:

DISTRO_FEATURES += "${DISTRO_FEATURES_LIBC}"

Apparently, DISTRO_FEATURES_LIBC was dropped in 2019 without me
noticing it and nothing was warning about that I was still using it.

The circular dependency problem was gone after removing this line.

Please, add this variable to the list of obsolete variables.

Thanks!
