One way to do this: make ARCH=sparc CROSS_COMPILE=sparc-leon-linux-gnu- HOSTCC=sparc-leon-linux-gnu-gcc Notice that I override HOSTCC as part of the make comand line. This allows me to override the "=" assignment in the top-level Makefile. But then my build breaks as fixdep do not run on my host. If you in general want to build a binary for the target then uapiprogs come in handy. Only caveat here is that you will be using the exported kernel headers.
