[mpsit] Eroare de compilare

[Alexandru Vaduva]

Astfel de flag-uri sunt enablate by default in Yocto, ele trebui sa existe
acolo si nu constituie sursa problemei.
Problema poate fi insa o contaminare a mediului de lucru (a hostului pe
care ai instalat Yocto).
Dupa o mai mare atentie acordata proiectului am ajuns la concluzia ca
aceleasi probleme se regasesc si in poky, branch fido.
Solutia ar fi un update de poky.
