From 9da1bf58b68d841e8f0ebb9350c8202500bb03a7 Mon Sep 17 00:00:00 2001 From: Daniel Dickinson Date: Tue, 10 May 2016 18:26:42 -0400 Subject: sdk: Fix keeping unset as unset The configuration preservation mechanism fails to keep items was are unset as unset. For busybox this causes issues when building with custom settings in the SDK. Therefore preserve busybox unset settings. In addition we preserve non-package selection unset settings because they may be important for making sure we compile and identical package for packages that are recompiled in the SDK. Now that SDK not longer ships .config this becomes relevant for any use of the SDK.
