New description:
As much as I understand, for building GCC with "graphite" one needs
`CLooG-PPL` (the Chunky Loop Generator) being installed. Note that `CLooG`
plus PPL seems not to be enough
Hence, I suggest to have an optional spkg. At least on openSuse, the
straight forward way to make an spkg (no patches, and an spkg-install and
spkg-check that just to `./configure --prefix...`, `make`, `make install`
and `make check`) seems to work.
This is related with #12369, and depends on #12672 and #12661.

Comment:
[http://groups.google.com/group/sage-
devel/browse_thread/thread/4e90520289b7b5ba/a84a9363d4ff6495 Leif] cited
from the GCC prerequisites page:
{{{
CLooG-PPL version( 0.15 or CLooG 0.16
Necessary to build GCC with the Graphite loop optimizations. There
are two versions available. CLooG-PPL 0.15 as well as CLooG 0.16. The
former is the default right now. It can be downloaded from
ftp://gcc.gnu.org/pub/gcc/infrastructure/ as cloog-ppl-0.15.tar.gz.
CLooG 0.16 support is still in testing stage, but will be the
default in future GCC releases. It is also available at
ftp://gcc.gnu.org/pub/gcc/infrastructure/ as cloog-0.16.1.tar.gz. To
use it add the additional configure option --enable-cloog-backend=isl.
Even if CLooG 0.16 does not use PPL, PPL is still required for
Graphite.
}}}
Actually, I found that `cloog-0.16.1` does not work, i.e., gcc does not
build. Hence, I made a cloog_ppl-0.15.11 spkg, that I suggest to make an
optional spkg.
