The children to inherit from were not sorted. This
wasn't a problem for list variables, because all those
inheritances get merged together based on the @inherit/
values in the list variables. But for single value variables
it made a difference.

Single-value product variables resolve to the first
instance of that variable in prefix order. What we
have right now is taking the value from the current
makefile if it's set, but if it's not, we take it
from the last child, not the first.
