You need to install a cross compilation toolchain. You can find
pre-built ones, for instance for armhf, you can use the linaro
toolchain. Cross-compilation toolchain programs names begin with a
string identifying the target architecture. For instance, linaro
toolchain compiler is arm-linux-gnueabihf-gcc. In order to cross-
compile a kernel for this architecture, you whould use
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
For the user-space part you need to pass the prefix without the final
dash to configure's --host option. As in:
./configure --host=arm-linux-gnueabihf
The installation procedure is described in README.INSTALL, see for
instance:
