sjg ca0319bf7c When evaluating condtionals from .if we want to require 
that the lhs is a variable reference, a number or a quoted string.
This helps avoid subtle bugs caused by typos.

When conditionals are being evaluated during variable expansion
we cannot be as strict becuase lhs will already have been expanded.

We therefor pass a boolean to Cond_EvalExpression to tell it how
lhs should be treated.

Add unit-tests/cond2.mk to test the above
