make qmake abort when $$prompt() gets EOF
otherwise, infinite loops can result, as amply demonstrated by the new
configure (which duly replicated the old configures' behavior ...).
QMakeEvaluator::evaluateBuiltinExpand() now returns a VisitReturn like
all other evaluate*() functions. the string list return value is now an
out parameter; i used a reference instead of a pointer to avoid
adjusting 56 usages of it.
Task-number: QTBUG-13964
