[OE-core] [PATCH 0/1] base.bbclass: Update the preferred_ml_updates

[Mark Hatle]

While working on a problem related to variable key expansion, I noticed
that the multilib PREFERRED_* expansion wasn't working exactly the way
it should have.  This patch addresses that issue.  Below is a diff of 
PREFERRED_* entries before and after this patch.
