[Buildroot] Cannot build C++ internal toolchain using uclibc-ng

[Michele Bucca]

Hello world, this is my first time using this project after a long
time. I'm trying to build a tiny system with a GUI (Minimal Xorg).
I'm using this as a reference
(https://agentoss.wordpress.com/2011/03/06/building-a-tiny-x-org-linux-system-using-buildroot/)
The problem regards the internal toolchain build: I enabled C++, Wide
Character support and Locale support
When I give the make command it gets stuck tryng to build
hotst-gcc-final-6.4.0: the error is the following:

My host system is Debian Jessie 8.10 x86_64
