  Log Message:
  -----------
  Change error for storage-class to mean linkage, fix lang-linkage diag

Allow multiversioning declarations to match when the actual formal
linkage matches, not just when the storage class is identical.
Additionally, change the ambiguous 'linkage' mismatch to be more
specific and say 'language linkage'.
