bitbake: data.py: Add a warning when expandKeys overwrites an existing key
When two variables are defined as: ${var} = "bar" foo = "foobar" The value of 'foo' when ${var} == foo becomes indeterminate. We want to warn a user when this situation has been encountered so they can take corrective actions. In the above example usually foo == bar, unless multilibs are enabled. Then ml-foo = "ml-foobar".
