Linux commit ID a4700a26107241cc7b9ac8528b2c6714ff99983d reserved 2 more
bits for the instructions darn (Deliver a Random Number) and scv (System
Call Vectored).
Linux commit ID 6997e57d693b07289694239e52a10d2f02c3a46f reserved
another bit for internal usage.
* sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_DARN and
PPC_FEATURE2_SCV.
* sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add scv
and darn.

Added hwcap2 bit masks for Power ISA 3.0 and VSX IEEE binary float 128-bit
features.

Linux commit b4b56f9ecab40f3b4ef53e130c9f6663be491894 introduced
a new HWCAP2 bit to indicate that the kernel now aborts a memory
transaction when a syscall is made. This patch adds that bit to
sysdeps/powerpc/bits/hwcap.h.

* sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_HTM_NOSC.
* sysdeps/powerpc/dl-procinfo.c:
(_dl_powerpc_cap_flags): Added descriptor for this hwcap
feature so it shows when LD_SHOW_AUXV=1.

Linux commit dd58a092c4202f2bd490adab7285b3ff77f8e467 added the
PPC_FEATURE2_VEC_CRYPTO auvx capability to indicate whether to
hardware supports vector crypto hardware instructions. This patch
adds its definition to powerpc hwcap bits.

elf/tst-auxv.c includes misc/sys/auxv.h, which ends up not actually
being included due to the guard overlap, and getauxval becomes an
implicit declaration and implicit pointer conversion which means, at
best, the test isn't actually testing what it thinks it is and, at
worst, it'll crash and burn on platforms where implict pointer
conversion is a Very Bad Thing.
* sysdeps/powerpc/bits/hwcap.h: Allow _SYSDEPS_SYSDEP_H guard as a
synonym for _SYS_AUXV_H to allow direct inclusion.
* sysdeps/sparc/bits/hwcap.h: Likewise.
* sysdeps/powerpc/sysdep.h: Define _SYSDEPS_SYSDEP_H instead of
_SYS_AUXV_H so we can include sysdep.h and sys/auxv.h together.
* sysdeps/sparc/sysdep.h: Likewise.
