[PATCH] ppc64: fix struct stat

Bug-Debian: https://bugs.debian.org/783292
Forwarded: http://www.zytor.com/pipermail/klibc/2016-January/003881.html

On ppc64 the struct stat defined by klibc matches the kernel one.
However it contains implicit padding before the st_rdev field due to the
64-bit alignement. For internal reasons, klibc defines st_rdev as a pair
of 32-bit values (using the __stdev64 macro). They only need to be
32-bit aligned and as a consequence st->st_rdev is incorrectly defined.

The solution is to add an explicit padding in the structure. This fixes
the resume binary on ppc64 BE and LE, and probably other things.
