I am glad you agree with me ;-). To be precise, however, I must say that
the snippet you cited does not apply here since it is talking about rule
definition while I was talking about target specific variable definition.
I don't think there is a part in the manual that specifies at what point
target-specific variables get expanded so it is in some sense an
implementation-defined behavior which, I must say, gets very tricky when
it comes to target-specific variable inheritance, +=, etc. I think
immediate evaluation is less surprising, though.
