There is insufficient evidence here to point at any one thing. I will
say that the threading dependency code has been around for a while and
most bugs like this turn out to be issues in the metadata, not bitbake.

When you say they were "not finished", what do you mean exactly?

Its normal they would still be packaging for example whilst gtk+ builds
since any dependency is on the populate_sysroot task of
pango-native/atk-native.
