[Buildroot] For buildroot 2013.08.1, Qt5OpenGL fails to build with ti-gfx support

[jiansong chen]

Hi all,

Att. I encounter the build failure issue when BR is configured to select
ti-gfx and QT5/eglfs. The build log sequence is as follows. Surprisingly by
nm from the same toolchain, the undefined symbols really appear in the
Qt5Gui library. I cannot figure out what's wrong. If more info is required,
please not hesiate to ask. Any suggestion is welcome. Thanks!

Best Regards,
Simon Chan

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr
