rpurdie pushed a commit to branch master-next
in repository openembedded-core.

commit 4202a09dece07c0d3f654c2b1ae504a031b4ee90

    utils: Add all_multilib_tune_list function
    
    Its useful to be able to query a list of variables to obtain the values
    in each multilib context. This adds such a function which works even
    if called in the non-default recipe context.
