We have been using Thud release from meta-arago and it builds Qt5.11.3
with EGLFS for AM335x.
Make sure add DISTRO_FEATURES_remove = "wayland" in your local.conf

And if you want QT5.12, then you can simply update meta-qt5 to warrior
but have to fix meta-arago Qt5 patches yourself
But most of them are around examples so can be skipped.

I have got dispensation from our client to use Thud so have checked out 
the appropriate branches for Poky, meta-ti, meta-arago, etc. into a new 
development directory.

What do you have the MACHINE and DISTRO variables set to in your 
local.conf and what image do you bitbake?

MACHINE is custom based on 'am335x-evm' and DISTRO is also custom
based on 'arago'
