Adding support for graphite to buildroot gcc toolchain

Thanks for pointing me to the buildroot patch submission site. Lets try again :)

This patchset add support for the graphite optimisation to the buildroot toolchain. Graphite has been around for quite some time and is almost standard is some distributions

The patchset consists of two new packages and a new flag in the supported gcc toolchains. I have omitted support for 4.5 as this might not work with the more recent version of cloog and isl, and if memory serves me correctly there was a transition from cloog-ppl to cloog around that time.

The impact is minimal as the flag is ordinarily disabled.

Cheers

Thomo

isl: new package
cloog: new package

Dear Steve Thomas,

Looks better, thanks. Though there is still one weird thing: normally git format-patch/send-email make the patch e-mails answers to the cover letter e-mail, so that they nicely appear as threaded.

Also, you still haven't taken into account the comments I made on your first version. Can you look at the entire e-mails
http://lists.busybox.net/pipermail/buildroot/2014-May/096954.html and
http://lists.busybox.net/pipermail/buildroot/2014-May/096955.html ? I suspect you overlooked the comments I made inline, in the various parts of your patch.

Thanks,

Thomas
