It's not only the type of variable that determines when it's expanded,
but also where the variable appears in the makefile. Some areas in a
makefile call for immediate expansion: basically any area which needs to
be expanded in order for the makefile to be parsed.
You can find a complete description of which areas of a makefile are
expanded immediately and which are deferred in the GNU make manual,
section "How 'make' Reads A Makefile".
