native/nativesdk: Use fixed DISTRO_FEATURES
There seems to be little advantage to letting distro features affect native builds. There is a significant disadvantage: a change to DISTRO_FEATURES will trigger a lot of unnecessary native tasks. In a test like this: $ bitbake core-image-minimal # append " systemd" to DISTRO_FEATURES $ bitbake core-image-minimal The latter build takes 44 minutes (28%) of cpu-time less with this patch (skipping 135 native tasks). Sadly wall clock time was not affected as glibc remains the bottleneck. Set native distro features to DISTRO_FEATURES_NATIVE appended with an intersection of DISTRO_FEATURES and DISTRO_FEATURES_FILTER_NATIVE. Current default values (baitbake.conf) are * DISTRO_FEATURES_FILTER_NATIVE ?= "api-documentation" (as gtk-doc-native has much less dependencies when built without it) * DISTRO_FEATURES_NATIVE ?= "x11" (to enable native UIs even if target does not containe them) Do the variable setting in native_virtclass_handler() because otherwise it could still be overridden by appends and the feature backfilling. Shuffle the early returns so DISTRO_FEATURES gets set as long as the packagename ends with "-native". Add similar variables for nativesdk. To make nativesdk work we need to enable the locale options so nativesdk-glibc-locales can build and to avoid the init manager check in the nativesdk case so add those fixes.
