[PowerPC] Add MultiarchIncludeDirs for powerpc64le

There was already partial support for multi-arch on powerpc64le,
but the MultiarchIncludeDirs setting was missing.  This patch
adds the appropriate definition, and also extends the
linux-header-search.cpp test case to verify an Ubuntu 14.04
powerpc64le tree.
