[PATCH 2/3] Documentation: use different label names for each arch's elf_hwcaps.rst

[Bagas Sanjaya <bagasdotme@gmail.com>]

Sphinx reported duplicate label warning:

WARNING: duplicate label elf_hwcaps_index, other instance in Documentation/arm64/elf_hwcaps.rst

The warning is caused by elf_hwcaps_index label name is already used for
arm64 documentation, whileas powerpc use the same name.

Disambiguate the label name for each architecture's documentation. While
at it, also adjust original reference in translated documentation.
