I made my setup (--> overriding DISTRO_FEATURES_BACKFILL by distro
configuration) working again by assigning it weakly in bitbake.conf:

-DISTRO_FEATURES_BACKFILL = "pulseaudio ${DISTRO_FEATURES_INITMAN}"
+DISTRO_FEATURES_BACKFILL ?= "pulseaudio ${DISTRO_FEATURES_INITMAN}"

ditto for MACHINE_FEATURES_BACKFILL.
