3.x branch does not compile on PPC

[Alex Yurchenko]

This is caused by aligned buffer implementation taken from chromium project:

In file included from ./chromium/compiler_specific.h:8,
                 from ./chromium/aligned_memory.h:39,
                 from galerautils/src/gu_reserved_container.hpp:19,
                 from galerautils/src/gu_vector.hpp:25,
                 from galerautils/src/gu_rset.hpp:16,
                 from galera/src/data_set.hpp:9,
                 from galera/src/data_set.cpp:5:
./chromium/build_config.h:117:2: error: #error Please add support for your
architecture in build/build_config.h

We either have to stop using it or fix that header.

Hi,
    I have encountred this bug on fedora BE machines. It seem there is some progress, but also more serious problems behind this. See fedora BZ https://bugzilla.redhat.com/show_bug.cgi?id=1092068 for more details.
