The following post on the Kodi forum gives details of how to run my build scripts:
My scripts might work for you as per the instructions in the thread, or you might need to tweak some of the dependencies depending on your OS. If you're already building LibreELEC using the standard build instructions ("PROJECT=imx6 ARCH=arm make release" etc.) then you shouldn't have too many issues - just make sure you install the dependencies required by my scripts (pv pxz pigz pastebinit patchutils).
Once you're setup (don't skip any steps in the post!) you can try "PROFILE=imx6 ./autobuild.sh" although I don't build the IMX6 project myself so have no idea if it will build successfully from LibreELEC master (in theory, it should). If you want to build from the libreelec-8.0 branch (with Kodi 17 final) then use "PROFILE=imx6-stable ./autobuild.sh"
Note that with my scripts when building with "PROFILE=imx6" you're basically building multiple moving targets - you're building latest LE master, latest Kodi master, and the latest masters for over a dozen different addons and libraries (libnfs/libcec), all of which are being updated daily (sometimes several times a day) with changes that can break your build. I update (at least once a day) oebuild.tar.gz with the latest commits and configuration changes to achieve a successful build but of course I'm only building for RPi/RPi2/Generic so you may need to resolve any IMX6-specific breakages yourself.
With "PROFILE=imx6-stable" you're building the LibreELEC/Kodi/addon/libnfs/libcec/etc. versions that are configured in LibreELEC branch libreelec-8.0, which should result in a more stable/predictable/reliable build environment.

Thank you for this valuable information. I will follow the thread and see if I can make it work.
