This is a new ELF dynamic tag that improves the size of relative relocations in shared object files and position independent executables (PIE). DT_RELR generation requires linker support for -z pack-relative-relocs option, which is supported for some targets in recent binutils versions.

It may or may not be worth adding words to imply that ld support for other targets will come in the future:)
