The question is why it's being included twice and why it's not getting
the right answers the first time. The fact that it isn't means
something's wrong; and if it *were* getting the right answers the
first time it wouldn't need to reset/change the variable.
(Plus, having the value change partway through evaluation of the
makefiles is probably worse than having it be wrong.)
All or almost all builtin.mk files are structured the same way, btw.
