No problem at all!

This note is also for the maintainers and other reviewers to say that we may
break the odroidc2 defconfig if this patch is applied.

As you can see this patch as been rejected following the Arnout's comments [1].
But still, gcc 4.9 will probably be removed before the next Buildroot LTS release.
