[OE-core] gl support for qemuaarch64

[John Ras]

Thanks Alex,

Yes i know, I'm targeting for arm though. I see '3d acceleration enabled'
so it was pointing me to its availability still without KVM. I was finally
able to have weston and its gl examples working for aarch64 and performance
seems reasonable. I'm still evaluating it though.


Br,
Joao
