## Here we check that can handle OVERLAY which will produce sections
## .out.big and .out.small with the same starting VAs, but different LMAs.
## Section .big is larger than .small, we check that placing of section
## .text does not cause overlapping error and that
## .text's VA is 0x1000 + max(sizeof(.out.big), sizeof(.out.small)).
