It looks like you cross compiled Qt having proper freescale binaries in
cross compilation sysroot. But on your device the EGL/GAL/VIVANTE/GLES
libraries are different. See:
http://download.ossystems.com.br/bsp/freescale/source/

And gpu related tarballs:

They contain freescale binaries with different configurations
(hardware/software floating point support, 3.0 or 3.5 kernel , quad or solo)

So from information you provided we can assume that the problem is related
to difference between core libraries, configuration in real system and
cross compilation sysroot.
