msba2 with gcc 4.9 2014q4 vs 4.8 2014q2


this mornings updates brought GCC 4.9 2014q4 to my system. Now I'm wondering which projects didn't work how exactly with the old gcc version so I can test whether to add it to the "working" section of the msba2 toolchain section in the RIOT wiki.

Cheers, Ludwig
