perf symbols: Fix annotation of objects with debuginfo files
Commit 73cdf0c6 ("perf symbols: Record text offset in dso to calculate objdump address") started storing the offset of the text section for all DSOs: if (elf_section_by_name(elf, &ehdr, &tshdr, ".text", NULL)) dso->text_offset = tshdr.sh_addr - tshdr.sh_offset; Unfortunately this breaks debuginfo files, because we need to calculate the offset of the text section in the associated executable file. As a result perf annotate returns junk for all debuginfo files. Fix this by using runtime_ss->elf which should point at the executable when parsing a debuginfo file.
