Why it's not needed anymore ?
Maybe add a previous patch to remove it before bumping bc ?

bc is in Buildroot mandatory dependency, so why not using bc from the host ?
Have you tried that ?
With that you can remove the dependency on host-ed and host-bc.

Is there any output format changes between bc version ?
