r14384 introduced use of getdents64 syscall and we missed a system call
value for MIPS64, so it broke the build for it. Add missing values now.

getdents has been deprecated since linux 2.4 and newer arches (arm64)
might no longer provide the getdents syscall. Use getdents64 for reading
the /proc/self/fd/ dir so --track-fds=yes works reliable on all arches.
Without this the none/tests/fdleak*vgtest might fail.

This caused memcheck/tests/linux/proc-auxv.vgtest to fail because

to add PPC64 LE support. The other two patches can be found in Bugzillas

POWER PC, add the functional Little Endian support, patch 2
The IBM POWER processor now supports both Big Endian and Little Endian.
The ABI for Little Endian also changes. Specifically, the function
descriptor is not used, the stack size changed, accessing the TOC
changed. Functions now have a local and a global entry point. Register
r2 contains the TOC for local calls and register r12 contains the TOC
for global calls. This patch makes the functional changes to the
Valgrind tool. The patch makes the changes needed for the
none/tests/ppc32 and none/tests/ppc64 Makefile.am. A number of the
ppc specific tests have Endian dependencies that are not fixed in
this patch. They are fixed in the next patch.

coregrind/m_dispatch/dispatch-ppc64le-linux.S. The same was done for
coregrind/m_syswrap/syscall-ppc-linux.S.

POWER PC, add initial Little Endian support
The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code. This patch adds the Little Endian #define ppc64le to the
Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.
The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific. The patch does not break the code for PPC64 Big Endian.
The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.

The semantics of XEN_DOMCTL_gethvmcontext are little interesting.
If the 'buffer' field of the structure is NULL, the hypercall is a request for
the required buffer size, which written into the 'size' paramater.
If 'buffer' is non NULL, Xen will write to the buffer, and update 'size' with
the amount of data written.
