As discussed in "[Openembedded-architecture] Yocto Compatible 2.0 +
signature changes", changes in .bbappend must depend on some explicit
configuration change, typically selecting a distro feature.
For _append and _remove, adding an override that is set only when the
corresponding entry is in DISTRO_FEATURES achieves that:
DISTRO_FEATURES = " ... my-distro-feature ... "
do_install_append_my-distro-feature () {
...
}
