Instead of generating offsets from early compiled object files (one day the offsets obtained from there might be changed during linkage stage) better to get them from a final stage where all object files involved are linked into complete binary blob. That happened that at early stage we indeed were using only single file per parasite and restorer but at present there a couple of file involved (and will be more in future) so we need a safe approach. Also note the symbols being exported are prefixed as "__export_". This is easier approach for now. Putting such symbols into separate section requires a way more efforts to handle. The main reason of having two files (Elf object and binary blob) is to get 1:1 mapping between symbols definition and their position in binary target. The exported symbols name addresses are obtained from object file and used as offsets in binary target.
