This looks to me like another "32bit toolchain caused stutter" like in bug 83436
Lorenzo, can you try how it goes if you add in your script also '-mtune' to both CFLAGS and CXXFLAGS ?
Yeah, looks like it's the same issue, btw I've rebuilded mesa with " .. -mtune=native -march=native .." and nothing change with newer 3.19 kernel.
I get 1 FPS in menus/settings and around 30 in game. With the 3.16rc6 I get always 60FPS (vsync enabled).
