This isn't official Wheezy, but it's what I've chosen to use to compile the DIET-PC armhf port. The reason being, Raspbian Wheezy is compiled with "-march=armv6 -mfpu=vfp" rather than "-march=armv7 -mfpu=vfpv3", which official Wheezy uses. This will allow DIET-PC armhf to run on less powerful hardfloat-capable platforms such as the popular Raspberry Pi.
