[Development] Qt5 Beta cross compiling problem

My mkspec was in a folder "linux-imx6". I always thought the mkspec-folder was
specified by the "-xplatform"-option in the configure-command?
Now, I simply changed it to "linux-g++-imx6" and tried to rerun configure and
make.
That seems to work, at least there are no obvious errors.

I tried both files with adapted configure-commands, but the best I could get was
an error from opengl es2.
That looked like a wrong path somewhere but I dropped that approach as my own
file worked fine so far.

I used the same file to cross-compile the Qt5-alpha, where I had no problems.
I thought using the same file for the beta would avoid problems that I had with
the alpha.

Thanks, I stumbled across that shortly after I tried to compile it without the
option, and that was a few minutes before you wrote.
