A section will be included if:
1. It is within the address space of the segment -- we use the LMA
if that is set for the segment and the VMA otherwise,
2. It is an allocated segment,
2. It is an allocated section or a NOTE section in a PT_NOTE
segment.
3. There is an output section associated with it,
4. The section has not already been allocated to a previous segment.
5. PT_GNU_STACK segments do not include any sections.
