[oe] [meta-oe][PATCH v3] glog: fixed the build for mips and other platforms

[Vyacheslav Yurkov]

From: Vyacheslav Yurkov <Vyacheslav.Yurkov at bruker.com>

According to build log http://errors.yoctoproject.org/Errors/Details/201286/
FindLibunwind wokred only for x86, arm, and x86_64. This patch extends the
cmake module to work with mips, ia64, ppc(64) and other architectures supported
by libunwind
