cpuinfo.sh outdated for mjpeg configuration ? (+ patch)

Hi all,

just found out that the cpuinfo.sh script turns out to be a bit an ancient one, it returns "core2" on my I7 system. Anyway, do we really need this script?
 GCC/Linux (since >= 4.?.? is perfectly fine  to find processor optimizations all by itself (-mtune=native), but i'm not aware of the others targets.

If no one objects, i'd submit following patch to  cpuinfo.sh (simply go for native on gcc/Linux systems)
