objdiff does show source line numbers if the object was compiled with debug information (DWARFv1 .line and DWARFv2+). Does your platform use a different line number format?
I just glanced at the agbcc repo and saw an interesting commit: https://github.com/pret/agbcc/commit/7b2372d922b6f76eac6166b270e421ce21eb583c
Could you try using -ffix-debug-line
?
like in decomp.me, makes decomping big functions easier
