bitbake.conf: DISTRO_FEATURES as overrides
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:
In local.conf:
DISTRO_FEATURES_append = " my-distro-feature"
In layer.conf:
DISTRO_FEATURES_OVERRIDES += "my-distro-feature"
In a .bbappend:
do_install_append_df-my-distro-feature () {
...
}
The subset of DISTRO_FEATURES that are made available as overrides
must be configured explicitly because using them this way should
be a conscious decision.
