A patch to reduce number of native dependencies has been posted to OpenEmbedded core mailing list. This patch should reduce amound of shared state required to build packages as it decouples some of default dependencies from native sysroot and should improve overall build times also. This however is not all rosy as it has unveiled a lot of packages requiring these default dependencies which would need to explicitly call them in the recipes. A common overlooked dependency is pkgconfig. This is not expected to go into upcoming October release but is more slotted for next LTS in April 2022.
