update-alternatives: Fix determinism issue
getVarFlags returns a dict and there is therefore no sort order. This means the order of the X_VARDEPS_X variables can change and hence the task checksums can change. This can lead to rebuilds of any parts of the system using update-alternatives and their dependees. This is a particular issue under python v3. Add in a sort to make the order of the variables deterministic. (From OE-Core rev: ecd1bfed5534f83b775a6c79092c04bd13c3af0a) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
