Arnout, thanks for the help.  I am at kernel version 4.9.147-ti-rt-121,
from an older TI-SDK for the Beaglebone X15.  Multiple people have added
quite a few drivers and configs to this code, it's locally stored for
Buildroot to use.  We have already tested quite a bit of our product
with what we have.  I really can't migrate to a new kernel at this point.
This whole exercise is all to get QT5-OpenGL enabled.  Any ideas on what
else I can do?

Thanks!
