Thanks, Eric,
As I was suspecting, wayland libs are required to be present for SGX to work
even in no-Wayland mode. Good thing OE detects those .so dependencies and
automatically pulls them in for you.
Have you tried removing Wayland pieces from the rootfs after the fact? I'm
guessing SGX would stop working due to dynamic linker/loader not being able to
resolve all the dependencies hardcoded in .so...
