Sounds like a good solution.
However, I still see two quite different cases here: When introducing
SELinux support we took great care that enabling SELinux at build-time
really only affecting kernel and kmods, hence we can do just phase1 and
provide only IB, SDK and kmods folder for each target (plus a bunch of
symlinks so opkg/IB will use the non-SELinux repos for everything
else).

When building with GCC 10 or NLS, this affects ALL packages, and hence
would need a complete phase1 and phase2 build, including all images
and packages.

Just keep that in mind, because it'd be sad to fork the entire
distribution just to enable SELinux eventhough that's not needed.
