File binutils-revert-rela.diff of Package binutils-2.39
This is for bsc#1198422 This essentially reverts commit 17c6c3b99156fe82c1e637e1a5fd9f163ac788c8 to return back to old behaviour regarding RELA relocs: old binutils used the relocated field as additional addend, relying on it being zero for normal RELA behaviour. This isn't correct according to the psABI, but some old tools (e.g. older ICC) emit object files where the in-field "addend" is to be used (and record the zero in the A field of the RELA reloc). This change was included starting with binutils 2.37, but for older codestreams we want to be compatible with the old (buggy) behaviour. We revert the change for all relocs and not just those for which it arguably made some sense or where we had a report about (PLT32).
