test the time it takes to build the kernel. first time is to preload the cache... take the time from the last run, real clock.

make CROSS_COMPILE=arm-eabi- distclean
cp venture-lt-config .config 
make ARCH=arm CROSS_COMPILE=arm-eabi- -j4 uImage
make CROSS_COMPILE=arm-eabi- distclean
cp venture-lt-config .config 
time make ARCH=arm CROSS_COMPILE=arm-eabi- -j4 uImage
