>From de209d23e5f571f03ff0efc6547a2ebbfae3828e Mon Sep 17 00:00:00 2001
From: Andreas Schwab <sch...@suse.de>

Subject: [PATCH] libelf: Sync elf.h from glibc
Adds PT_RISCV_ATTRIBUTES, SHT_RISCV_ATTRIBUTES, PT_AARCH64_MEMTAG_MTE,
RELR definitions, LoongArch relocations.
dwelf_elf_e_machine_string was updated to handle EM_LOONGARCH, and
ebl_dynamic_tag_name was updated to handle the new RELR dynamic tags.
