debug/elf: support relocations relative to sections with non-zero addresses commit 72ec930fa70c20ce69b21bf32a7916c04c2e9c2f added basic support for relocations, but assumed that the symbol value would be 0, likely because .debug_info always has address == 0 in the ELF section headers. CL 195679 added further support for relocations, but explicitly encoded the original assumption that section addresses would be 0. This change removes that assumption: all relocations will now be properly computed based on the target symbol value even when that symbol is a section with a non-zero address. Typically, sections that are part of a LOAD program segment have non-zero addresses. For example, .debug_ranges relocations could be relative to .text, which usually has an address > 0.
