Patch 8 in a series of cleanup patches from Will Schmidt

Add a helper script to determine if the platform is ppc64le.
This is specifically used to help exclude the 32-bit tests from being
run on a ppc64LE (ABIV2)  platform.  The 32-bit targets, specifically ppc32/*
is not built on LE.
This patch fixes Vagrind bugzilla 347322.
