From c876d3bbefe0dc00c27ca0c12d29da5874946962 Mon Sep 17 00:00:00 2001 From: Dominik Riebeling Date: Wed, 15 Dec 2021 21:04:28 +0100 Subject: rbutil: Merge rbutil with utils folder. rbutil uses several components from the utils folder, and can be considered part of utils too. Having it in a separate folder is an arbitrary split that doesn't help anymore these days, so merge them. This also allows other utils to easily use libtools.make without the need to navigate to a different folder.
