This topic looks reccurent with rpi-userland on buildroot (for example [1])

This is because somes headers are in interface/vcos/pthread/ instead of 
interface/vcos

This proble is solved in qt with linux-rasp-pi-g++ device qmake 
configuration[2] but buildroot use a specific device to ease the 
toolchain integration.

I'm not sure how to handle this issue. Should I make a specific hook for 
rasp-pi (and maybe rasp-pi2) or should i try to replace buildroot 
specific device with real ones?

Bernd, Yann, any advice?
