ARC: update definitions in elf/elf.h
While porting ARCv2 to elfutils [1], it was brought up that the
necessary changes to the project's libelf/elf.h must come from
glibc, because they sync it from glibc [2]. Therefore, this patch
is to update ARC entries in elf/elf.h.
The majority of the update is about adding new definitions,
specially for the relocations. However, there is one rename, one
deletion, and one change:
- R_ARC_JUMP_SLOT renamed to R_ARC_JMP_SLOT to match binutils.
- R_ARC_B26 removed because it is unused and deprecated.
- R_ARC_TLS_DTPOFF_S9 changed from 0x4a to the correct value 0x49.
Finally, a specific SHT class for ARC has been added to glibcelf.py.
Else, it would result in a collision:
_register_elf_h(Sht, ranges=True,
File "/src/glibc/scripts/glibcelf.py", line x, in _register_elf_h
raise ValueError('duplicate value {}: {}, {}'.format(
ValueError: duplicate value 1879048193:
SHT_ARC_ATTRIBUTES, SHT_X86_64_UNWIND

No regression has been observed after applying this patch. Below
