Add platform files for BlueGene/P systems

BlueGeneP-base:    Internal base shared by static and dynamic files
BlueGeneP-static:  Platform file for all-static builds

+# by the real platform files.  Use one of these two platforms instead:
+#
+#     BlueGeneP-dynamic  For dynamically linked builds
+#     BlueGeneP-static   For statically linked builds
+#
+# This platform file tries its best to adhere to the behavior of the MPI
+# compiler wrappers included with the latest BG/P drivers.
+#
+
+
+#
+# For BGP builds, we're cross compiling, but we don't want to re-root things
+# (e.g. with CMAKE_FIND_ROOT_PATH) because users may have libraries anywhere on
+# the shared filesystems, and this may lie outside the root.  Instead, we set the
+# system directories so that the various system BGP CNK library locations are
+# searched first.  This is not the clearest thing in the world, given IBM's driver
+# layout, but this should cover all the standard ones.

+# Most of these directories are the includeand lib directories for the frontend on BG/P systems.
+# Not ignoring these can cause things like FindX11 to find a frontend PPC version mistakenly.

+# the filesystem, and we can't re-root ALL backend libraries to a single place.
