[arch-dev-public] [signoff] glibc-2.11 toolchain rebuild

I have put the glibc-2.11 toolchain rebuild in [testing]. Apart from glibc-2.11, the kernel header patch level got bumped to the latest version and I took a newer snapshot of the binutils-2.20 branch. From a quick look at the changelog there should not be a lot of issues compiling stuff like previous glibc/gcc releases. As always, it has be well tested in Fedora and you should look there for any patches needed. Signoff both, Allan
