Best way to update gnu-config?

[Marcin Juszkiewicz <marcin.juszkiewicz@linaro.org>]

[-- Attachment #1: Type: text/plain, Size: 430 bytes --]

I am working on meta-aarch64 layer to add 64-bit ARM support.

For that I have to update gnu-config to newer version. Currently I am
using gnu-config_git.bbappend to move to 20120814 one. OE-Core is using
tarball prepared by Yocto Project so update is not so easy for outside
developer.

Attached are files which I am using (including updated uclibc patch).
Please reply with information how I can get it fully merged.
