commit c77eecdc35e2fb4664765264a72ed3f29e50c047

    Upgrade Cabal submodule to latest HEAD, change to package key calculation.
    
    Summary:
    One notable change is that the package key calculation algorithm in Cabal
    has changed (from an undocumented format based on Show instances to a fully
    specified format), so you will need to do a full rebuild.
    
    I'd greatly prefer if this could be merged to 7.10.
