This fixes compile issues on powerpc with gcc 5 which show up with
errors like:

I am fine witj this patch for now, since we are mostly build testing,
we have to keep in mind
its a codegen bug and can bite us at runtime. I am just hoping for an
update to this patch and that will eliminate
that doubt.

Agreed, an update upstream would obviously help. FWIW the automated
runtime tests did look reasonable on the autobuilder apart from:
core-image-sato-sdk has a problem with the C++ toolchain not finding
limits (all arches).
qemuarm is not booting (minimal, sato or sato-sdk).
However these issues were present before the patch so I don't think its
related.
Since the failures list is better with the patch I'll merge it until
something better comes along.
Cheers,
Richard

hmm thats interesting. Can you point to an error for more details ?

yes I have had problems with linux-yocto on emulator too.
