Tweaked the previous to eliminate .module_base and output build_id_offset as 
follows:


@@ -5376,9 +5379,10 @@ dump_unwindsyms (Dwfl_Module *m,
      if (modname == "kernel")
        c->output << ".build_id_offset = 0x" << hex << build_id_vaddr - (base 
+ extra_offset)
                  << dec << ",\n";
+    // ET_DYN: task finder gives the load address. ET_EXEC: this is absolute 
address
      else
        c->output << ".build_id_offset = 0x" << hex
-                << build_id_vaddr - base
+                << build_id_vaddr /* - base */
                  << dec << ",\n";
    } else
      c->output << ".build_id_len = 0,\n";

  for ET_EXEC we get e.g. 0x40024c
  for ET_DYN we get e.g.  0x1a0
  for kernel we get e.g.  0x430544
