hmmm... weird, I cannot reproduce it. Did you applied patch named "qt5base: 
fix Vivante x11/EGL configuration"?

Just in case it would be useful, you will find my .config here:

Well, if we want to keep it as minimalist as possible, we should not enable 
gpu-viv-bin-mx6q. But, it does not make sense to enable gpu-viv-bin-mx6q if 
there no library to use it.

In add, I read in Buildroot Developer Days from ELCE 2013 report[1] that BR 
will begin to adding 'demo' config.

Finally I enabled Qt. 

I confess I have hesitated to send this patch as is, exactly for reasons you 
gave (and the more time passes the less I am convinced by my arguments).
