[PATCH] libelf: Sync elf.h from glibc

[PATCH] libelf: Sync elf.h from glibc

[Andreas Schwab]

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.

Hi Ying,

Thanks pushed.

BTW. Even these patches do require a Signed-off-by normally.
But I checked it is exactly the same as the one in glibc elf/elf.h.

Cheers,
