File binutils-revert-rela.diff of Package binutils.26690

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).
