The GNU PROPERTY constants seem to change from time to time. See e.g. the last glibc elf.h sync: commit 31d551ae4dd8cf307c68f86b6c1ecac2f92b522a Author: Mark Wielaard <mark@klomp.org> Date: Thu Mar 24 23:06:09 2022 +0100 libelf: Sync elf.h from glibc. Adds EM_INTELGT, NT_ARM_TAGGED_ADDR_CTRL, NT_ARM_PAC_ENABLED_KEYS, ELF_NOTE_FDO, NT_FDO_PACKAGING_METADATA and OpenRISC 1000 specific relocs. It also adds and renames some GNU_PROPERTY constants. But none of the constants the elfutils code uses was renamed or given a different constant value. dwelf_elf_e_machine_string was updated to handle EM_INTELGT.
