[oe] gcc -4.7 available for testing

[Khem Raj]

Hi OEers

Since gcc-4.7 branch has been started I have prepared initial set of
recipes for it which are here

http://git.openembedded.org/openembedded-core-contrib/log/?h=kraj/gcc-4.7

(You need the top 3 patches really)

It can build sato images and minimal images in OE core for all
supported qemu machines

GCC test results are here

http://sakrah.dontexist.org/files/gcc-4.7-tests/

if you are using oe-core settings then you need is set

GCCVERSION = "4.7%"

in local.conf

Enjoy
