[Khem Raj]

Hi

GCC 4.7.0 has been released and I have updated the recipes and I have 
been using them for past 3-4 weeks. I was able to build sato images for 
both uclibc and eglibc and also meta-toolchain targets for all combos 
Please help in testing them and report
any issues you see.

The branch is

http://git.openembedded.org/openembedded-core-contrib kraj/gcc-4.7

Thanks
