  |     lto/122515: Fix archive offset types for i686
  |     
  |     On i686, offsets into object archives could be 64-bit, but they're
  |     inconsistently treated across the lto, which may sometimes result in
  |     truncation of those offsets for large archives.
  | ... 36 lines of the commit log omitted.
