[Buildroot] Compilation error of Buildroot with X server

[Damien Borie]

OK. So I have restarted everything with the new buildroot version. I 
have started configuration from the beginning, but based on my old 
.config. Compilation has been long (QT...). Now I got a cleaner project!
But finally, I have the same error exactly.
I forgot a detail : I use a external toolchain made with Crosstool, and, 
as it was working for the precedent target (and it's the same target), I 
used the same toolchain.
I join the .config. For all X11 parameters, I kept default.

Thanks.
Damien.
