I have quite new CPU (i7-4770K) and old version of Ubuntu (12.04 LTS 64-bit).

It was not possible to compile 3.7RC7 with default settings, the compilation
stopped with unknown assembly instructions when old gcc didn't recognize Haswell
architecture's native instructions.

I query-replaced march=native with march=corei7 from configure file and after
that all went normally.

I can't say if the speed suffered, but now it shows all 8 (virtual) cores in
100% load when rendering and it is much faster than my older i5-750 rig.
