Even though this is only RC1 it's been heavily used internally so it should not be any worse than existing arc-2014.12. Moreover this relase (and so its RC1) finally delivers support of NPTL for ARC in uClibc. That's why it would be good to allow interested users to start trying it (for example WebKit and apps that use WebKit could be successfully built and run) also it will be helpful to run that new toolchain through autobuilder in attempt to find any hidden regressions so we have a solid toolchain for release. If there's an interest in that patch more patches will follow with subsequent RCs and essentially on appearence or relese Buildroot will be updated with it.
