cloog: new package

CLooG is a free software and library to generate code for scanning
Z-polyhedra.

cloog is needed for the optional graphite optimisations that are
supported by gcc since version 4.5. Therefore this package is required
for the toolchain to support graphite.

Graphite optimisations primarily involve loop blocking flattening and
interchage so are probably of mimimal use in an embedded system where
small sizes are favoured.

cloog depends on isl.

[Thomas:
 - Add patch to add missing CMake related files to the release
   tarball, preventing the build from succeeding.
 - bump to 0.18.2
 - disable libtool patch, which doesn't apply]

+Add CMake related files missing from the release tarball
+
+Due to a bug in the cloog release, a few files were missing from the
+release tarball. This patch re-adds those files, which are needed for
+the build to work. This patch can be dropped when cloog is bumped.
